This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1999-2004 Chevrolet Silverado 1500 and GMC Sierra 1500 (5.3L).
The K&N 77-3021KP High-Flow Performance intake system is designed to provide a guaranteed increase in horsepower and torque by replacing the restrictive factory air filter and intake housing. This system features a mandrel-bent aluminum intake tube with a polished finish, ensuring smooth, laminar airflow directly to your engine. It is paired with an oversized, conical High-Flow Air Filter featuring oiled cotton media, which can go up to 100,000 miles between cleanings under typical highway conditions.
To protect the intake charge from high engine bay temperatures, this kit includes a custom-engineered heat shield that isolates the filter from radiant heat. Designed for a straightforward installation, the entire system typically bolts on in less than 90 minutes using existing factory mounting points.

- Tube Material: Mandrel-bent aluminum
- Finish: Polished
