MotoGP Air Filter Cleaner Kits, Motorcycle Waterproof Air Filter Rain Sock Dustproof Protective Cover Fits for Harley (Size S), Black#S

I bought this before going on an extended trip, knowing that I would have limited access to be able to clean my filter. This is a great product to catch some excess dust before entering the filter!! Washes nicely and fits well! I will be buying more of these to have on hand!!

I was surprised of the construction of the pre-filter. It is made with quality material for a low cost.Seller has been added to favorites.

Worked perfectly for what I needed it for

It fits over the whole air filter and it works for keeping water out, but I got the small and it's still huge.

This Prefilters is a tight fit but works on Amazons Universal 3 inch intake Red Filter just fine. You do have to work at it but its put together well and is half the price of others. As to how long it will last will be time will tell. But it great for now. Thanks S Thompson , Oregon
