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.

As always, K&N filters are awesome!! This filter was purchased for my new 2013 Honda Rancher - more power, easy clean up, & easy install. I run K&N filters on ALL of my vehicles: 04 Silverado 2500HD, 2003 S-10 ZR5, 1994 Jeep Wrangler YJ & now the Honda. Thank you K&N for a great product! The shipping was fast & free.
