About K&N
K&N developed this NextGen system around the packaging and airflow demand of the listed 5.7L V8 vehicles. The American 6063 aluminum with a gunmetal finish path works with a vehicle-shaped semi-enclosed airbox and an oversized oiled cotton gauze filter rather than a universal tube-and-filter combination.
Related Parts
- No internal product is linked because replacement filters, cleaning supplies, and companion intake parts must match K&N 70-9036 and the exact 5.7L V8 configuration.
FAQ
What is the 70-9036?It is the K&N NextGen intake system for the supported 5.7L V8 applications.
Does the intake require a tune?No tune is required for the published gains on the supported stock calibration.
Is the filter washable?Yes. Service it with the procedure appropriate for its listed filter media.
How often should the filter be serviced?K&N states up to 100,000 miles under normal highway conditions; inspect sooner in severe dust or off-road use.
Is it legal for use in California?No. K&N lists this intake as not legal for sale or use in California on pollution-controlled motor vehicles.

Will it fit a different engine in the same model?No fitment is implied for another engine. This listing requires the 5.7L V8 configuration and a supported canonical application.
What should be checked after installation?Verify every clamp, seal, sensor connection, wiring clip, and hood clearance, then inspect for air leaks or warning lights.
Installation Instructions
- Confirm the exact vehicle, 5.7L V8 configuration, and K&N 70-9036 before removing the factory inlet.
- Read the current K&N instructions, disconnect the battery if directed, and inventory the tube, airbox, filter, couplers, clamps, brackets, seals, and hardware.
- Remove the factory airbox and inlet components without damaging sensors, wiring, vacuum lines, or fresh-air ducting.
- Transfer only the sensors and fittings identified in the instructions, then assemble the application-specific airbox and intake tube without leaving debris in the inlet path.
- Install the washable filter and Quick-Lock interface, align every coupler, and tighten clamps in the documented sequence.
- Reconnect all sensors and the battery, verify hood and moving-part clearance, start the engine, and inspect for leaks or warning lights before driving.
