Overview: If you’ve ever wanted to know if a car’s high-performance air filter makes a difference, or if your small filter is killing horsepower, you’ve come to the right video! In this episode of Engine Masters, presented by AMSOIL, we test a whopping 19 different combinations of filter sizes and styles including paper elements, K&N filters, stock housings, dual-snorkle housings, velocity stacks, filtered lids, and way more—all the way up to some shocking results with tablewear! Our test engine is a 750-horsepower, 496ci big-block Chevy, but the data we gathered is relevant for any engine down to about 300 horsepower. Engine Masters is supported by Mr. Gasket, Earl’s Vapor Guard Hose, Permatex, and Auto Meter.
