K&N's Universal Air Filters are a top - choice for a wide range of applications such as racing vehicles, radio - controlled cars, generators, snowmobiles, and tractors. No matter the air intake's angle or offset diameter, there's likely a perfect K&N filter for your equipment. These filters feature ultra - strong molded pliable rubber flanges. They absorb vibration, ensure a secure fit, and can be stretched up to 1/16 of an inch (1.5mm) to fit between sizes. Best of all, they're washable and reusable. This filter fits multiple vehicle models including the 2001 - 2002 BMW 525i, 1999 - 2000 Honda Civic in various trims, 2009 Mazda MX - 5 Miata in different versions, 2002 Mini Cooper S, and 2004 Volkswagen Golf GTI VR6.












Using your K&N Universal Air Filter is easy. First, find the right spot for it based on your equipment's air intake. Make sure the filter is properly aligned and then attach it securely using the rubber flanges. If it's a bit of a tight fit, you can stretch the flanges up to 1/16 of an inch (1.5mm). When it comes to maintenance, since the filter is washable and reusable, it's a great cost - saver. You can wash it periodically. Just use a mild cleaner and water, then let it dry completely before reinstalling. A dirty filter can affect your equipment's performance, so keep an eye on it. Also, make sure the filter is always properly attached to prevent any air leaks. That's all you need to know to keep your K&N Universal Air Filter working well.
