A 4Runner that runs dusty roads clogs paper filters quickly, and each replacement is one more thing to carry and forget. Washing a single filter beats buying a new one every season.
The K&N High-Flow engine air filter uses four layers of oiled cotton gauze to block and trap contaminants, and it only needs cleaning every 75,000 miles under normal highway driving. It arrives pre-oiled, drops into the factory air box, and has a No-Hassle Lifetime Limited Warranty.
Pull the old filter and drop this one in.
