WORKS Drop-in High Performance Air Filter

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 for the Evolution X. 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. The reusable element is easily cleaned, re-oiled and back in your factory airbox in a matter of minutes with the WORKS Service Kit. 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 X filter on the market! Combine our WORKS filter with the StealthWORKS Performance Muffler for even more performance gains.

great filter

maperformance is the only place where i can shop with piece of mind, about the filter nothing to say about it no problems works great as always, made my ''stock'' evo a little bit louder

Better than OEM

Works drop in filter

Great filter very solid and tight snug fitment, and not to pre oiled as most drop in filters. I felt the difference from my old k&n filter , especially on the throttle. Awesome filter, if you can get your hands on one, I would get it.

Good buy

I bought this air filter on a whim and man I don’t regret it car pulls hard and I get to hear all types of turbo noises without going full cone filter can’t recommend this enough.

Feels and Sounds great!

It’s a significant improvement over the stock air filter. Boost noises are louder and a little more fun to drive. If it wasn’t so tempting to floor it I’d have an increase in mpgs as well
