K&N's Universal Air Filters are a top - choice for a wide range of equipment 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 K&N filter that fits your needs. These filters feature ultra - strong, molded pliable rubber flanges. The flanges absorb vibration, ensure a secure fit, and can be stretched up to 1/16 of an inch (1.5mm) to bridge size gaps. What's more, they are washable and reusable, offering long - term value and convenience.












Using your K&N Universal Air Filter is easy. First, find the right spot in your equipment's air intake system. Make sure the filter's flange fits well and attach it securely. If the size is a bit off, you can stretch the flange up to 1/16 of an inch (1.5mm) to get a proper fit. When it comes to maintenance, regularly check the filter for dirt and debris. Once it gets dirty, it's time to clean it. You can wash the filter with a mild cleaner and water. Let it dry completely before putting it back in. Always keep an eye on how your equipment performs with the filter. If you notice any issues, double - check the installation. That's it! With proper use and care, your K&N filter will serve you well for a long time.
