Do not assume it fits a bike or engine that is not named here; ask the store first. - [Pit Bike Engine Parts > AIR FILTER OUTERWEARS](https://tboltusa.com/store/pit-bike-engine-parts-air-filter-outerwears-c-51_1110.md) Where a fitment line says "All", it means all years of the model named on that line, not all bikes. ## Description (the store's own text) **Application:** - PT-3424 UNI Filter OUTERWEARS COMPACT PREFILTER has been specifically made for the new UNI 2 in 1 compact air filters. Impermeable to water and dirt, the outerwears cover keeps your air filter clean and dry and keeps your ride breathing fresh, clean air even on the dirtiest of days. A must for anyone that plans on tearing up the track or trails. Washable and Usable with simple slide over installation. Outerwears Pre-filters are designed to enhance the efficiency of any performance or exposed air filter. The Pre-filter is constructed with a proprietary polyester mesh with uniform micron openings, treated with an optional hydrophobic water-repellent process. The mesh is UV resistant, filters debris down to .005”, is shatter proof in freezing temperatures, and resistant to heat up to 450 degrees. The material is puncture resistant and has elasticity characteristics allowing the threads to return to the original position in the event the threads have been impacted or shifted. The manufacturing process incorporates a welded seam for strength, or reinforced industrial grade thread to fill needle holes and to reduce potential failure points in the material. Pre-filters are designed to deflect the damaging debris, which clogs air filters, compromising peak air-flow and horsepower. The Pre-filter also extends the time between servicing intervals reducing costs and increasing convenience for the consumer. ## Shipping and returns - Flat rate shipping is $8 for parts orders under $75 and free for most parts orders over $75, within the continental 48 states.
