OuterwearsOuterwears Air Filter Wrap, Pre Filter, 3-1/2 in OD, 4 in Tall, Top, Polyester, Black, Each

If you run a pitbike woth an open filter buy these. No and ifs or buts. If you’re lazy and don’t take care of your stuff. This is for you. This is also for me bc I race pitbikes in the woods. Wonderful thing for the air filter

Perfect fit for pitster pro xjr90 air filter. Install in 10sec. Supreme quality

Fit as described, good quality, very easy to clean, serves it's function by keeping dust out of filter overall very good value for the cost.

Good filtration, price too high

I purchased this Outerwears - Air-Filter Pre-Filter Cover for a UNI - 2-Stage Foam Clamp-On Air-Filter to have triple filtration & have the cleanest possible air entering my engine. I use these on every single UNI - 2-Stage Foam Clamp-On Air-Filters I have on my Off-Road machines (three total) & they make my air-filters last 3-5 times longer & extend the period between air-filter cleanings. This is an excellent product that any kind of clamp-on air-filter should have installed on it, cotton gauze or foam style air-filters. I totally recommend this product to anyone & it is one of the best investments you can do to your air-filter to ensure it is getting maximum filtration. This product is worth every single penny & then some.

Fits perfectly on my 48mm nibbi racing cone filter

Used it over uni filter

Haven’t ridden with it yet, since my tube is currently popped but I’ve had one before, fits as it should and resist water nice so now I can splash thrue puddles. If you put it under the hose clamp it will 100 percent seal off your filter from fine dust, must have if you run a pod, Good price too 👍🏼
