After talking to K&N’s Product Specialist, Scott Holst, at the 2012 SEMA Show, it’s easy to see why the brand has become one of the most recognizable brands in the industry. For over 40 years, K&N has created innovative air filters and air intakes to increase your ride’s overall performance. In their SEMA booth, they had several intake systems on display. We checked out popular intakes for the Chevy Silverado, Chevy Camaro and Subaru WRX STI. Each intake has impressive, individual power gains.
