The factory airbox on your 5.7L HEMI Ram 1500 was engineered for silence and cost — not performance. The sealed plastic housing with its flat paper filter restricts airflow to the HEMI's 345-cubic-inch V8, especially under load when you're towing, merging, or running through the gears.
The Flashark cold air intake replaces the entire restrictive factory system with a mandrel-bent aluminum intake tube, oversized conical dry filter, and black steel heat shield that isolates the filter from underhood heat soak. The 3.5" diameter aluminum tube provides a smooth, turbulence-free airflow path from filter to throttle body — no corrugated rubber hose, no crushed bends, no factory baffles choking the HEMI's appetite for air. You'll feel a quicker throttle response, a deeper intake growl that the factory airbox deliberately muffles, and a noticeably stronger pull through the mid-range.
Key Features
3.5" Mandrel-Bent Aluminum Intake Tube — Black powder-coated finish; smooth internal bore eliminates turbulence from the factory corrugated rubber hose and restrictive baffles; powder-coat resists underhood heat soak, corrosion, and engine bay chemicals
Oversized Conical Dry Cotton Filter — High-flow dry cotton gauze element — no oil required, no MAF sensor contamination risk, no over-oiling-induced check engine lights; washable and reusable for the life of the truck
Black Steel Heat Shield — Powder-coated steel heat shield isolates the filter from radiant engine bay heat; keeps intake charge temperatures closer to ambient, preserving air density and HEMI efficiency under sustained load and towing
Bolt-On Installation — Uses factory mounting points; reuses the stock mass airflow (MAF) sensor without an adapter; no cutting or drilling.
7-10% Horsepower & 5-7% Torque Gain — On a stock 5.7L HEMI (395 HP / 410 lb-ft), expect approximately 28-40 HP and 20-29 lb-ft of additional output; gains are most pronounced when paired with an exhaust upgrade or mild tune; standalone gains typically 10-15 whp
Up to 50% Increase in Airflow — 3.5" mandrel-bent tubing + oversized conical filter deliver dramatically more CFM than the stock flat paper filter and corrugated rubber intake hose
Aggressive HEMI Intake Sound — The open-element filter eliminates the factory airbox's sound dampening; you'll hear the deep HEMI V8 intake growl under acceleration — the sound the factory sealed airbox deliberately suppresses
Improved Throttle Response & Mid-Range Pull — Reduced intake restriction lets the 5.7L HEMI breathe freely through the RPM range; most noticeable under load — towing, passing, and highway merge acceleration feel sharper and more responsive
Washable & Reusable Filter — Clean every 10,000-15,000 miles with mild soap and water; no replacement filters to buy — the included dry cotton filter lasts the life of the truck under normal use

| Years | Make | Model | Engine |
|---|---|---|---|
| 2009-2010 | Dodge | Ram 1500 | 5.7L V8 HEMI (345 cu.in.) |
| 2011-2018 | Ram | 1500 | 5.7L V8 HEMI (345 cu.in.) |
| 2019-2023 | Ram | 1500 Classic | 5.7L V8 HEMI (345 cu.in.) |
Q: Which Ram 1500 models does this cold air intake fit?
A: This cold air intake kit is designed for 2009-2018 Ram 1500 and 2019-2023 Ram 1500 Classic equipped with the 5.7L HEMI V8 (345 cu.in.). The 2009-2010 models were branded "Dodge Ram 1500" — they use the same DS-platform intake architecture and are fully compatible. The 2019-2023 Ram 1500 Classic continues the same 4th-generation (DS) body style and intake layout. It does NOT fit the 2019+ Ram 1500 (new DT platform), 3.6L V6, EcoDiesel, or Ram 2500/3500 models.
Q: What's the difference between Ram 1500 and Ram 1500 Classic?
A: Starting in 2019, Ram sold two different Ram 1500 models simultaneously. The Ram 1500 Classic is the continuation of the 2009-2018 fourth-generation (DS platform) — same body, same engine bay, same intake system. The Ram 1500 (non-Classic, DT platform) is the completely redesigned fifth-generation model with a different engine bay layout, different intake routing, and different throttle body position. This intake fits the Classic only. Quick visual check: if your 2019+ truck has the older crosshair grille design, it's a Classic. If it has the new streamlined grille, it's the DT model — this intake will NOT fit.
Q: How much horsepower will this 5.7L HEMI cold air intake add?
A: On a stock 5.7L HEMI (395 HP / 410 lb-ft), expect approximately 7-10% horsepower gain (28-40 HP) and 5-7% torque gain (20-29 lb-ft). Actual gains vary with truck condition, elevation, tuning, and other modifications. Standalone dyno gains typically fall in the 10-15 whp range; the upper end of the claimed range is achievable when paired with an exhaust upgrade and mild tune. The intake's primary value is reducing intake restriction and supporting airflow — it works synergistically with other performance upgrades.
Q: Does this cold air intake require a tune?
A: No tune is required for basic installation. The factory ECU automatically accommodates the increased airflow. You will not get a check engine light from installing this kit on a stock 5.7L HEMI Ram. However, a custom tune can help maximize performance when the intake is combined with exhaust headers, a cat-back system, throttle body upgrade, or other major modifications. Many Ram 1500 HEMI owners run this intake on stock programming with no issues.
Q: Will this intake make my 5.7L HEMI louder?
A: Yes — and most HEMI owners consider that a feature, not a drawback. The open-element conical filter eliminates the factory airbox's sound dampening, making the deep HEMI V8 intake growl significantly more noticeable under acceleration. You'll hear a throaty, aggressive intake note that the factory sealed plastic airbox deliberately suppresses. It's sporty but not obnoxious — the sound is most pronounced under hard acceleration and quiet at idle and cruise.
Q: Will this cold air intake fit my Ram 2500 or 3500 with the 5.7L HEMI?
A: We cannot confirm fitment on Ram 2500 or 3500 models. While the 5.7L HEMI engine is shared across Ram 1500, 2500, and some 3500 models, the engine bay layout, intake routing, and airbox mounting points differ between the half-ton and heavy-duty trucks. Some competitors offer separate CAI kits for the 2500/3500 with different heat shield designs. If you have a Ram 2500 or 3500, contact us at service@flasharkracing.com before ordering to verify compatibility.
Q: Will this intake improve fuel economy on my Ram 1500?
A: Fuel economy improvements are possible but not guaranteed. Some drivers report a small MPG increase (0.5-1.5 MPG) when the HEMI breathes more efficiently, particularly during highway cruising. However, tire size, axle ratio, towing weight, driving habits, and vehicle condition have a far larger impact on fuel economy than the intake alone. Don't purchase this product solely for fuel savings — buy it for the throttle response, sound, and performance gains.
Q: Can this intake cause a check engine light on my Ram?
A: A correctly installed intake should not cause a check engine light. The factory MAF sensor transfers directly to the new intake tube — no adapter or spacer needed. Problems typically arise only from incorrect installation: a disconnected sensor, loose clamp, air leak at a silicone coupler, or a component installed in the wrong position. Before starting the engine after installation, inspect all couplers, clamps, sensor connections, and vacuum hoses. Recheck all connections after the first few heat cycles.
Q: Is the included air filter washable and reusable?
A: Yes. The kit includes a washable and reusable conical dry cotton gauze filter — no oil required. Unlike oiled filters that can contaminate the MAF sensor if over-oiled, the dry cotton media flows freely and requires no oiling after cleaning. Clean every 10,000-15,000 miles with mild soap and water, let air dry completely, and reinstall. No replacement filters to buy — the included filter lasts the life of the truck under normal use.
Q: How difficult is the installation? Can I do it myself?
A: Yes — installation is straightforward and typically takes 45-60 minutes with common hand tools. The process involves: (1) removing the factory airbox, intake tube, and flat paper filter; (2) positioning the steel heat shield using factory mounting points; (3) installing the 4" aluminum intake tube with silicone couplers and clamps; (4) mounting the conical dry filter; (5) transferring the MAF sensor to the new tube; (6) verifying all connections. No cutting, drilling, or fabrication required. Detailed instructions are included in the kit. Recheck all clamps after the first 3-5 heat cycles as silicone couplers settle.
Q: Does this intake fit the eTorque 5.7L HEMI models?
A: Yes. The eTorque mild-hybrid system is a belt-driven motor-generator unit that replaces the traditional alternator — it does not modify the intake system, throttle body position, or airbox mounting points. The intake routing and sensor locations are identical between eTorque and non-eTorque 5.7L HEMI models on the Classic (DS) platform. This kit fits both configurations. The eTorque system operates independently of the air intake and will not be affected by this upgrade.
Q: How does this intake compare to K&N, aFe, or S&B for the Ram 5.7L?
A: The Flashark cold air intake uses the same core design philosophy as premium brands: a mandrel-bent aluminum tube, dry cotton gauze filter, and steel heat shield. The 4" tube diameter is competitive with or larger than most alternatives (aFe uses 3.5", K&N varies). The dry filter eliminates the MAF contamination risk of oiled filters from K&N and aFe's Pro 5R line. The Flashark kit delivers comparable airflow and performance gains at a significantly lower price point — typically 40-60% less than K&N or aFe for the same application. All required hardware and detailed instructions are included.
