2019 Toyota Tundra 4.6L V8 Cold Air Intake FAQs

Q1: Is this cold air intake legal in my state?

A1: This kit does not carry a CARB Executive Order (EO). It is not legal for sale or use in California (and other CARB-adopting states) for street-driven vehicles; in those jurisdictions, it is intended for off-road and competition use only. It is legal in the 49 non-CARB states for street use on the Fitment-listed vehicles. Always check your local and state laws before installation.

Q2: Will this fit my Toyota Tundra?

A2: It is engineered for the 2012–2019 Toyota Tundra 4.6L V8 (1UR-FE). It does not fit the 5.7L V8 (3UR-FE), 4.0L V6 (1GR-FE), or the newer 3.4L Twin-Turbo V6 (V35A-FTS) Tundra. If your Tundra is a 5.7L, this is the wrong kit — we offer a matched Flashark Cold Air Intake Kit for 2012–2015 Toyota Tundra 5.7L V8 for that engine. Message us with your engine code if you're unsure which kit fits your Tundra.

Q3: How much horsepower will this add?

A3: Typical intake-only gains for this application are approximately +3–10 hp and +3–10 lb-ft of torque on the stock 4.6L V8. Actual results depend on the vehicle's condition, ECU calibration, supporting hardware, and how the kit is installed. We don't publish a single hp figure for intake gains — they're inherently variable from one vehicle to the next.

Q4: Will a cold air intake improve my MPG?

A4: MPG is dominated by driving habits; an intake alone can't guarantee a measurable gain. Expect the main benefit as throttle response and intake tone rather than fuel economy. If hyper-miling is your goal, an intake is not the right upgrade.

Q5: Will this void my warranty?

A5: Under the Magnuson-Moss Warranty Act, an aftermarket part cannot void your factory warranty unless the manufacturer proves the part caused the failure. This kit is designed as a direct bolt-on replacement that keeps factory sensors and connections at their OEM locations and bores.

Q6: Will it throw a check engine light (CEL)?

A6: This kit is engineered to retain the factory MAF sensor at the OEM location and bore, which keeps the MAF calibration within the OEM design envelope. CELs are usually caused by an intake leak, an over-oiled filter, or a sensor that's been dislodged during install — review the install steps before buttoning everything up.

Q7: Do I need a tune after installing?

A7: No tune is required. The kit is fully compatible with the factory ECU on 2012–2019 Toyota Tundra 4.6L V8 (1UR-FE) models when installed as directed.

Q8: Is this safe in rain or deep water?

A8: Normal rain driving is fine — the filter pulls air from the fender well. Avoid deep water crossings; water ingestion into the intake can cause hydrolock and severe engine damage. If you regularly ford water, consider a high-mounted or snorkel-style relocation kit. For a deeper dive on what normal intake-air temps look like under heat-soak versus ambient conditions, see our Normal Intake Air Temperature at Idle guide.

Q9: How do I clean the filter?

A9: The dry synthetic cone filter is washable and reusable — no oil required. Use a mild filter cleaning solution, rinse thoroughly with clean water, and let it air dry completely before reinstalling. Do not apply oil; oil can migrate to the MAF sensor and trigger a CEL.

Q10: What does it sound like?

A10: You'll hear a deeper, throatier intake tone under acceleration; at cruise the cabin stays comfortable. Sound is subjective, but most 4.6L Tundra owners describe the result as a muscular V8 note rather than a raspy one. For context on what's normal after intake and exhaust mods, see our NVH After Car Mods guide.

Q11: What's included / what do I still need?

A11: The kit ships with the aluminum intake tube, dry conical air filter, steel heat shield, three silicone couplers, and a hardware pack. The factory MAF sensor is reused from your vehicle (not included in the box). You'll need basic hand tools — a socket set, screwdrivers, and pliers — and about 50–75 minutes.

Q12: Will it work with my aftermarket throttle body?

A12: This kit is engineered for the factory 4.6L throttle body. If you've installed an oversized aftermarket throttle body, verify the coupler diameter with our support team before ordering — the silicone couplers in this kit are sized for the OEM throttle body bore.

Q13: Will this fit a TRD Off-Road, TRD Pro, or other TRD trim Tundra?

A13: Trim packages such as TRD Off-Road, TRD Pro, and Limited are appearance, suspension, or feature packages — they don't change the engine or the factory intake tract. As long as your Tundra is the 4.6L V8 (1UR-FE) from 2012–2019, this kit fits regardless of trim.

Q14: What is the 1UR-FE engine, and why is this kit tuned for it specifically?

A14: The 1UR-FE is Toyota's 4.6L V8 used in the 2012–2019 Tundra (and the related Sequoia). The factory intake tract on this engine prioritizes sound suppression with baffled plastic tubing, which chokes airflow and lets under-hood heat soak the charge. This kit replaces the airbox and intake tube with a smooth mandrel-bent aluminum tube and a sealed heat shield pulling from the fender well — a configuration the 5.7L Tundra (3UR-FE) and 4.0L V6 (1GR-FE) cannot use because their factory MAF locations and bores are different.
