Q: Why do I need to clean my MWR Air Filter?
A: MWR uses a proprietary Biodegradable Air Filter Oil that uses it's unique properties to trap air contaminants and protect your engine. During the course of normal riding and track days, the oil becomes saturated with those contaminates and no longer provides optimal performance, requiring you to wash the "used" oil off of the MWR air filter material and prepare it for reapplication of MWR's oil.

Q: Can't I just use regular soap?
A: The MWR Biodegradable Air Filter Cleaner is specifically formulated to ensure it does NOT damage your MWR air filter material. You may be able to achieve similar cleaning results with different soap, but why run the risk of harming your air filter? After all, it's job is to protect your motorcycle's engine. Don't mess around with that.

Q: What is the oil I need to reapply to the filter?
A: After cleaning all of the old oil from your filter, it's required to reapply Biodegradable Air Filter Oil.

Q: How long will it take for me to receive this once I order it?
A: Please see the articles in our support center regarding domestic and international shipping.

Q: I'm located outside of the United States. Will I have to pay duties on this item?
A: Some countries charge additional fees when a package is imported and delivered to the recipient. We have no way of knowing or estimating what these fees will be. It is the buyer's responsibility to cover these additional costs.
