This was a filter manufactured by K&N around 2010. After much research in 2023 this filter is no longer available, and K&N has no interest in producing it again. Some may still be available from other sites as NOS, buyer beware. See available filter to see our recomendation for the replacement.
28-4200 was 6" deep.
K&N designed two hood scoop air filters to fit the unique shape of the Don Davis drag racing hood scoop. Due to the various configurations of the engine compartment and drag racing cars, the depth of the air filter must be considered. K&N's 28-4195 has a 10" depth. The 28-4200 has a depth of 6 inches. Both have a black powder coated base and are simple to mount into a Don Davis hood scoop.
K&N racing filters use two layers of cotton gauze that allow plenty of fresh air to enter the engine. The 28-4195 and 28-4200 deliver this powerful air-flow while protecting your engine from small stones, tire dust and other track debris that could damage your engine.
