K&N 99-04 Chevy Silverado / GMC Sierra V6-4.3L Performance Intake Kit

If you're looking to get a little more out of your 1999-2006 Chevrolet Silverado 1500 or GMC Sierra with the V6-4.3L engine, this K&N performance intake kit is a solid option. It's designed to help your engine breathe easier, which can lead to a noticeable improvement in power. K&N guarantees an increase in both horsepower and torque with this system.

The kit uses a high-density polyethylene (HDPE) tube that's rotationally molded to help increase the volume of air going into your engine. It comes with a washable and reusable High-Flow Air Filter made with oiled cotton media. This oversized, conical filter is built to last, and you can typically go up to 100,000 miles between cleanings under normal driving conditions. To keep that cooler air from getting heated up by the engine bay, a custom heat shield is included. Most people can get this installed in under an hour.

This K&N intake system is protected by K&N's Million Mile Limited Warranty, and it won't void your vehicle's factory warranty. Keep in mind that some performance intakes are not street legal in California due to emissions regulations, so check the product specifications for CARB status if you're in that state.
