Outerwears Prefilter

I am using this on a unifilter in my sxs. Our trails are mostly sand and fine dirt so there is a lot of dust, these help keep that fine dust and water from getting to the foam filter. This cuts down on how frequently you have to wash the foam filter which is annoying to do. I put one on everything with a foam filter and never had any issues.

Extra protection, easy to clean, durable, and they prolong your primary filter. I've used these for years on various applications.

Works as described. Very well I love it when I’m a pinch take this off and clean it because the filter under it is still dang clean. I use this on my cf moto with a uni filter. I have a uTibe channel called RedNeckGarage check it out. A ton of cf moto videos on there.

This prefilter measures approximately 4” x 6” or 115mm x 155mm. I bought it hoping it would work over the K&N filter on a Pitster Pro 140. It does fit, its just much bigger than the question answered above states.

works great, glad I purchased it

Very nice prefilter, helps keep the larger particles out of the air filter.We also put one over the end of the air intake tube to keep the bigger stuff out, that way it won't fill the air box with as much dust.

Too small for my application

I love the added filteration it adds to my filter for the dusty Southern Utah trails. Fit over my Uni UP-6229ST filter perfectly.
