Product Description

The K&N 33-2129 is a washable, reusable drop-in replacement air filter engineered for the GMT800 and GMT900 full-size GM truck and SUV platform - covering the Chevrolet Silverado 1500, Tahoe, Suburban, Avalanche, GMC Sierra 1500, Yukon, Yukon XL, and Cadillac Escalade from 1999 through 2020. Fitting the complete range of naturally aspirated V6 and V8 engines from the 4.3L through the 6.0L, this filter drops directly into the factory airbox with zero modification and is fully compatible with OEM MAF sensors and engine electronics.

Built for the demands of daily driving, towing, and hauling, the K&N 33-2129 only needs cleaning every 75,000 miles - making it a practical long-term performance upgrade for one of the most popular truck platforms ever built. With over two decades of confirmed fitment across multiple model generations, it's one of the most widely used drop-in filters available for full-size GM vehicles.
