Toyota's 2TR-FE 2.7L four-cylinder is legendary for durability — 300,000-mile examples are common. But Toyota prioritized silence over airflow. The factory airbox routes intake air through a maze of baffles and resonators designed to mute every hint of engine noise, at the cost of throttle response and breathing efficiency. For a 159-horsepower engine pushing a 4,000-pound truck, every restriction matters.
Flashark's cold air intake replaces the entire factory airbox assembly with a mandrel-bent, black powder-coated aluminum intake tube, a high-flow, washable, dry conical filter, and a formed steel heat shield. The smoother, larger-diameter tubing eliminates the factory baffles and resonators, reducing intake restriction and allowing the 2TR-FE to breathe more freely. On a stock engine, expect 3–5 WHP with the most noticeable improvement being throttle response — the delay between pressing the pedal and the engine responding shrinks noticeably.
Installation is straightforward: remove the factory airbox, bolt in the heat shield bracket, connect the intake tube with the supplied silicone couplers and clamps, transfer your MAF sensor, and attach the filter. No cutting, no permanent modifications, fully reversible. Expect 45–75 minutes with basic hand tools. The result is a Tacoma that responds more quickly, sounds more purposeful under acceleration, and retains the 2TR-FE's legendary reliability — no tune required; the factory ECU adapts on its own.
Key Features
Mandrel-Bent Black Powder-Coated Aluminum Intake Tube — High-quality aluminum tubing with a durable black powder-coated finish for heat resistance and corrosion protection. Larger inner diameter than the restrictive factory plastic plumbing, with its noise-canceling baffles.
High-Flow Washable Dry Conical Filter — Red dry media filter engineered for high airflow with excellent filtration. No oil required — simply wash with mild soap and water, dry completely, and reinstall. Dry media eliminates the risk of MAF sensor contamination associated with over-oiled cotton filters.
Formed Steel Heat Shield — Sturdy steel shield isolates the filter from direct radiator and exhaust manifold heat. Includes a rubber edge seal that contacts the hood when closed, creating a semi-sealed cooler air zone around the filter.
Improved Throttle Response — Reducing intake restriction means the 2TR-FE responds to pedal input sooner. The delay between pressing the accelerator and the engine reacting shrinks noticeably — the most practical daily-driving benefit on a 4-cylinder truck.
3–5 WHP Gain — Modest but real power gain on the naturally aspirated 2TR-FE. The 2.7L is a detuned reliability engine from the factory; an intake alone won't transform it, but it removes one of the factory's intentional breathing restrictions.
Enhanced Intake Sound — Under acceleration, the intake produces a deeper, more purposeful induction growl that replaces the muted silence of the factory airbox. At steady cruise, sound levels remain close to stock — no highway drone.
2nd Gen & 3rd Gen Compatible — Fits 2005–2015 (2nd gen) and 2016–2019 (3rd gen) Tacoma with the 2TR-FE engine. Toyota carried the same 2.7L engine across the generation change, and the intake mounting points remained consistent.
2WD & 4WD Compatible — Drivetrain configuration does not affect intake fitment. The intake path and sensor connections are identical between 2WD and 4WD models.

2005–2019 Toyota Tacoma 2.7L L4 Cold Air Intake FAQ
Q1: What vehicles does this 2.7L Tacoma cold air intake fit?
A1: This cold air intake kit is designed for 2005–2019 Toyota Tacoma models equipped with the 2.7L 2TR-FE inline-4 engine. It is compatible with both 2WD and 4WD configurations as long as the engine type matches the listed application.
Q2: Does this intake fit the Toyota 2TR-FE engine?
A2: Yes, this intake is designed specifically for the Toyota 2TR-FE 2.7L engine found in Tacoma models within the 2005–2019 range. Always confirm engine displacement before ordering.
Q3: Will this fit both 2WD and 4WD Tacoma models?
A3: Yes, drivetrain does not affect intake fitment. This kit works on both 2WD and 4WD Tacoma models as long as they use the 2.7L engine configuration.
Q4: Does this cold air intake increase horsepower?
A4: A cold air intake can improve airflow efficiency, leading to modest horsepower gains typically in the 3–8 HP range on a naturally aspirated 2.7L engine. The most noticeable improvement is throttle response and engine sound rather than large power increases.
Q5: Will this intake improve fuel economy?
A5: Fuel economy improvements are not guaranteed. While smoother airflow may slightly improve efficiency under light throttle, real-world MPG depends more on driving habits, tire size, load, and maintenance condition.
Q6: Will this intake cause a check engine light (CEL)?
A6: A properly installed intake should not trigger a CEL. If a warning appears, it is usually due to vacuum leaks, loose clamps, or incorrect MAF sensor installation rather than the intake itself.
Q7: Is this compatible with off-road driving and dust conditions?
A7: Yes, but maintenance is important. The reusable filter is designed for performance airflow, but in dusty or off-road environments it should be cleaned more frequently to maintain engine protection.
Q8: Will this intake work on a lifted Tacoma?
A8: Yes, it can be installed on lifted Tacomas as long as the intake routing and sensor connections remain compatible. Some lifted setups may require checking hose tension and clearance.
Q9: Does this intake require a tune?
A9: No tune is required for a stock 2.7L Tacoma. The ECU can adapt to increased airflow. However, tuning may improve performance if combined with exhaust or other engine modifications.
Q10: Will this make my Tacoma louder?
A10: Yes, it produces a more aggressive intake sound during acceleration and higher RPMs compared to the stock airbox, while remaining relatively quiet during cruising.
Q11: Is this a true cold air intake or short ram intake?
A11: Depending on installation position, it can function as either. If the filter is positioned away from engine heat, it behaves as a cold air intake; if mounted in the engine bay, it behaves more like a short ram intake.
Q12: Will this cause water ingestion (hydrolock risk)?
A12: There is a small risk if the filter is exposed to deep standing water. Normal rain is safe, but avoid flooded roads and deep water crossings to protect the engine.
Q13: Is installation difficult?
A13: Installation is straightforward and typically takes 45–90 minutes using basic hand tools. No cutting or permanent modification is required.
Q14: Does this improve throttle response on the 2.7 Tacoma?
A14: Yes, reduced intake restriction improves airflow, which results in slightly quicker throttle response, especially at mid to high RPM ranges.
Q15: What is the main benefit of upgrading the stock airbox?
A15: The main benefits are improved airflow efficiency, better throttle response, enhanced induction sound, and a reusable high-flow filter compared to the factory airbox system.
| Years | Make | Model | Engine | Generation | Drivetrain | Notes |
|---|---|---|---|---|---|---|
| 2005–2015 | Toyota | Tacoma | 2.7L 2TR-FE I4 | 2nd Gen | 2WD & 4WD | All trim levels (Base, PreRunner, SR5) |
| 2016–2019 | Toyota | Tacoma | 2.7L 2TR-FE I4 | 3rd Gen | 2WD & 4WD | All trim levels (SR, SR5) |
Q1: Will this fit my 2nd gen Tacoma (2005-2015) AND my 3rd gen (2016-2019)?
A: Yes. Toyota carried the 2TR-FE engine across the generation change, and the intake mounting points, MAF sensor housing diameter, and engine bay clearance remained consistent. Both 2nd-gen (2005–2015) and 3rd-gen (2016–2019) Tacomas with the 2.7L four-cylinder use the same intake kit. Always verify your engine code — the emissions label under the hood should read "2TR-FE."
Q2: Does this fit the V6 Tacoma (4.0L or 3.5L)?
A: No. This kit is designed exclusively for the 2.7L 2TR-FE four-cylinder engine. It will NOT fit the 4.0L 1GR-FE V6 (2005–2015) or the 3.5L 2GR-FKS V6 (2016–2019). The V6 engines use different intake manifold flange patterns, throttle body diameters, and MAF sensor housings. Installing this on a V6 Tacoma will result in a physical fitment failure at the throttle body.
Q3: What are the actual horsepower gains on the 2TR-FE?
A: Expect 3–5 WHP on a stock 2.7L engine. The 2TR-FE is a 159-horsepower factory engine designed for reliability and longevity, not peak output. Toyota intentionally restricts intake breathing for NVH (noise, vibration, harshness) reasons. Removing those restrictions recovers some of that lost efficiency, but this is not a 10+ horsepower modification. The real gains are in throttle response — the 2TR-FE feels noticeably more eager to rev — and intake sound character. Claims of 10+ HP from an intake alone on a stock 2TR-FE are not realistic.
Q4: Will this improve my Tacoma's fuel economy?
A: Do not expect measurable MPG improvement. The 2TR-FE in a 4,000+ pound truck with brick-like aerodynamics is already working hard. While reduced intake restriction can marginally improve pumping efficiency at light throttle cruise, real-world MPG is overwhelmingly determined by driving style, tire size and pressure, payload, and terrain — not the intake. If fuel economy is a primary concern, an intake is not the solution.
Q5: Will this cause a check engine light (CEL)?
A: A correctly installed intake should NOT trigger a CEL. The 2TR-FE's factory ECU uses closed-loop fuel trim compensation with the MAF sensor and adapts to modest airflow changes on its own. If you do get a CEL after installation, check the following in order: (1) vacuum leak at a coupler connection — spray carb cleaner around joints while idling and listen for RPM change; (2) MAF sensor installed backwards — the arrow on the MAF housing must point in the direction of airflow toward the engine; (3) MAF sensor not fully seated or connector not clicked in; (4) PCV hose disconnected or cracked during installation. Clear the code, fix the issue, and verify it does not return.
Q6: Is this a true cold air intake or a short ram?
A: This is a short ram intake with a heat shield — not a true fender-well cold air intake that routes the filter behind the bumper. The formed steel heat shield and rubber hood seal create a semi-enclosed cooler-air zone around the filter, separating it from direct heat from the radiator and exhaust manifold. A short-ram design is the practical choice for a truck: it eliminates the deep-water-crossing risk of a low-mounted fender-well filter, simplifies installation, and still provides significantly better airflow than the restrictive factory-baffled airbox. The heat shield is functional — it will reduce intake air temperatures compared to an unshielded open-element filter — but it does not achieve the near-ambient IATs of a true fender-well cold air intake.
Q7: Do I need a tune after installing this intake?
A: No. The 2TR-FE's factory ECU uses a MAF-based closed-loop fuel control system that continuously adjusts short-term and long-term fuel trims to maintain the target air-fuel ratio. It will adapt to the modest increase in airflow from this intake on its own. A tune is not required for safe operation. If you combine this intake with a full exhaust system (header + cat-back), a tune could help optimize the combined changes, but it remains optional rather than mandatory.
Q8: Will this make my Tacoma louder?
A: Yes, under acceleration. The factory airbox is designed with multiple resonators and baffles specifically to mute intake noise. Removing it reveals the 2TR-FE's natural induction sound — a deeper, throatier growl when you get on the throttle. At idle and steady highway cruise, the sound increase is minimal. Around town with stop-and-go acceleration, you will notice the difference. It is purposeful, not obnoxious — more like the engine finally sounds like a 2.7-liter rather than a sewing machine.
Q9: How does the dry filter compare to oiled cotton filters?
A: The dry synthetic media filter in this kit requires no oil for filtration. This eliminates two risks associated with oiled cotton gauze filters: (1) MAF sensor contamination — over-oiled filters can deposit oil residue on the MAF sensor's hot wire, causing incorrect airflow readings and drivability issues; (2) improper cleaning — incorrectly re-oiling after cleaning can leave dry spots (poor filtration) or over-saturated areas (MAF contamination). The dry filter is simply washed with mild soap and water, air-dried completely, and reinstalled — no oil, no guesswork. Toyota MAF sensors on the 2TR-FE are particularly sensitive to contamination, making the dry media design a practical advantage.
Q10: Is this safe for off-road and dusty conditions?
A: Yes, with adjusted maintenance. The dry filter provides excellent filtration for normal on-road driving. In dusty off-road conditions, the filter will load up faster, and you should check and clean it more frequently — every 5,000 to 8,000 miles instead of the standard 15,000–20,000 miles. The short-ram design with a heat shield also has an advantage over low-mounted fender-well intakes: the filter is positioned higher in the engine bay, reducing its exposure to dust clouds kicked up by the front tires on dirt trails.
Q11: What about deep water crossings — is there a hydrolock risk?
A: The short ram design positions the filter near the top of the engine bay, significantly higher than a fender-well cold air intake. This means the filter sits well above the factory water fording depth recommendations for the Tacoma. Deep water that would submerge a low-mounted filter would also flood the cabin and likely stall the engine from other causes first. That said, no intake makes your engine waterproof — if water reaches the filter, the engine will ingest it. Avoid crossing water deeper than the bottom of the front bumper.
Q12: How difficult is the installation? Do I need a mechanic?
A: Installation is straightforward for anyone comfortable with basic hand tools. You will need: 10mm and 12mm sockets, a flathead and Phillips screwdriver, and pliers for hose clamps. The process: (1) disconnect the negative battery terminal, (2) unplug the MAF sensor connector, (3) remove the factory intake ducting and airbox, (4) bolt in the heat shield bracket using existing mounting points, (5) install the new intake tube with silicone couplers, (6) transfer the MAF sensor to the new housing, (7) attach the filter. No cutting, drilling, or permanent modifications required. Budget 45–75 minutes. A mechanically inclined owner can do this in a driveway; no professional mechanic needed.
Q13: Will this fit with aftermarket accessories (winch, dual battery, etc.)?
A: The intake occupies the factory airbox location on the passenger side of the engine bay. The most common aftermarket accessories (winch, dual battery tray, onboard air compressor) are installed on the driver's side or in the front bumper area and do not interfere. However, if you have a custom accessory mounted in the passenger-side engine bay near the factory airbox location, verify clearance before ordering. The heat shield adds approximately 1.5 inches of depth compared to the factory airbox.
Q14: How often should I clean the filter?
A: Every 15,000–20,000 miles under normal on-road driving conditions. Under dusty off-road conditions, reduce to every 5,000–8,000 miles. Cleaning procedure: (1) remove filter from intake tube, (2) tap gently to dislodge loose debris, (3) rinse with low-pressure water from the inside out (clean side to dirty side — never from the outside in, which pushes debris deeper), (4) wash with mild soap and warm water, (5) rinse thoroughly from inside out, (6) allow to air dry completely — do not use compressed air or heat, which can damage the media fibers, (7) reinstall once fully dry. Never install a wet filter — the moisture can contaminate the MAF sensor.
Q15: Will this void my Toyota warranty?
A: In the United States, the Magnuson-Moss Warranty Act prevents manufacturers from voiding your warranty simply because you installed aftermarket parts. A warranty claim can only be denied if the aftermarket part is proven to have directly caused the failure. For a 2005–2019 Tacoma, most vehicles are well past their factory warranty period, making this a non-issue for most buyers. If your Tacoma is still under a Toyota extended warranty or Certified Pre-Owned coverage, consult your service advisor — some dealerships are more modification-friendly than others.
