Air Filters For Dirt Bikes From Rocky Mountain ATV/MC

If there’s one thing that dirt bikes are good at, it’s kicking up roost on a dry motocross track or cruising a dusty mountain trail. As an off-road enthusiast, you know that dirt is simply part of the game. After all, you can’t have a dirt bike without the dirt! While sending dust flying every which way can be a lot of fun, it can be brutal on your bike’s engine. That’s why regularly replacing your engine air filter is an absolute must.

Dirt bike air filters are specially designed to withstand the rigors of off-road riding, and Rocky Mountain ATV/MC carries some of the most popular choices around. From leading brands like No Toil, Twin Air, Uni and PC Racing, you have air filter replacements to suit your particular style. (If you prefer sticking with stock air filters, check out our OEM section.) Many of our motorcycle air filters are built with dual-layer foam, capturing large dirt grains as well as minute dust particles without sacrificing your engine’s performance. This keeps your bike’s engine in top shape while allowing you to drive it for long periods of time. What’s even better is that with a little bit of cleaning and reapplication of oil, many of these filters are reusable! We also carry a variety of useful air filter accessories, including seals, filter skins and air box washing covers.

    King Quad Air Filter Improvement

    Prior to purchasing this filter, I used the UNI with the stock air box lid which did not seal well along the top surface of the air box as you could still see the foam filter around the extruding around the lid. With this Twin Air System, it comes with a much better lid which has a rubber seal around it that helps to keep water out, especially when in deeper water holes. The filter is easy to remove and clean as well.

    Cheaper then others and very good product

    The video for this product shows them using only an arousal spray can to clean the box then it being wiped with a paper towel. Who does that? I had concerns if it would not keep water out when cleaning with a hose. It worked great. It has no tabs to line up on the air box but on a modern KTM it is pretty much a no brainer if you have it on right or not. Item allows lots of access to the area so you can get a soapy cloth in the box and get it really clean. I then hosed it out with a garden hose. Not one drop made it past the cover. The exhaust plug is kind of a joke but at the price is pretty much an extra "free" item anyway.
