It's the best air filter. I use this filter (RU-4740) on my Honda TRX450r for many years, great quality. Thanks

Increased HP and .5 to 1 mpg increase. One indirect problem. The air box on the Tundra sits on top of the main wiring harness. The K&N intake opens the space and makes for a nice nesting area for squirrels. Wire insulation is made with peanut and vegetable oils to prevent cracking, creating a magnet for squirrels, rats and mice. I had my 2011 Tundra 1 month before having it towed to Toyota. Wiring harness replacement was $5300.00. Solution is a pepper embedded electrical tape sold by Honda. I have all wires wrapped and no squirrel problem since.
