Using your K&N Custom Round Racing Assembly is easy. Just install it onto your single or two barrel carburetor following the standard installation procedures. When it comes to cleaning, the high - flow air filter is washable. Simply remove it, wash it gently with mild soap and water, let it dry completely, and then reinstall. As for maintenance, check the filter regularly, especially if you drive in dusty conditions. Replace the filter if it's damaged. And always make sure the custom chrome top and base plates are securely attached to keep the filter in place and performing at its best.
