The K&N cold air intake system for GM Silverado/Sierra 1500 V8 (2009–2013) uses a mandrel‑bent aluminum tube and a washable, reusable High‑Flow air filter to increase horsepower and torque. The oversized conical filter can go up to 100,000 miles between services under normal highway use; a heat shield helps isolate intake air, and most installations complete in under 90 minutes.
