PC Racing Filter Skin 6-8"X4-7"

I feel like most riders don't know these exist - and they are an incredible, simple product! Double or triple your air filter cleaning intervals running these. No kidding ... and I am a maintenance nut. My approach is to install a clean air filter at the beginning of every season and just swap out these pre-filters as they get dirty (assuming the main filter is still clean and wet/tacky). I usually go a whole season without having to change the main air filter, which is about 15-25 hours for me. I've been running these since 2003 and have never looked back. Great product, great results/protection, super convenient, major time saver.
