Better air flow means more power. Cleaner air means increased engine longevity. Now you can have the best of both worlds with the WORKS High-flow Drop-in Air Filter.

This direct drop-in replacement for the factory filter retains stock drivability and can flow more than twice as much as the stock filter. Constructed of multilayer, uniform cotton fabric with stainless steel mesh reinforcement, this unit will filter particles down to several microns with very high saturation capacity.

Pays for itself after only 3 to 4 scheduled maintenance periods and lasts a lifetime! Includes one carefully pre-oiled filter and simple installation instructions. This is the best air filter on the market! Combine our WORKS filter with the StealthWORKS Performance Muffler for even more performance gains.

 - Direct drop-in replacement for the factory filter
