Using your K&N Universal Air Filter is easy. Just find the right spot for it based on your equipment's air intake system and attach it securely using the rubber flanges. Make sure it fits well and there are no gaps. When it comes to maintenance, keep an eye on how dirty the filter gets. Once it looks dirty, it's time to clean it.
