K&N 99-04 Chevy Silverado V8-6.0L Performance Intake Kit

This K&N 57-3023-1 performance intake kit is designed for 1999-2007 Chevrolet Silverado trucks with the V8-6.0L engine, as well as many compatible Cadillac, GMC, and Chevrolet models. It replaces your factory air intake system to help your engine breathe more freely, which can result in a noticeable increase in horsepower and torque. This kit is a solid option if you're looking to get more out of your truck's engine.

The kit features a rotationally-molded high-density polyethylene (HDPE) tube, which is shaped to help increase the volume of air entering your engine. It comes with a washable and reusable high-flow air filter that uses oiled cotton media. This oversized, conical filter is designed to last up to 100,000 miles between cleanings under normal highway driving conditions. A custom heat shield is included to help block hot air from the engine bay, ensuring your engine gets cooler, denser air. Installation is typically straightforward and can often be completed in under an hour.

K&N backs this intake system with their Million Mile Limited Warranty, and it's designed not to void your vehicle's factory warranty. Remember that some intake systems are not street legal in California due to emissions regulations; always check the product specifications for CARB status if you are in California.
