K&N 63 for 2015 Tundra
The K&N kit is very nice and appears to be high quality. I had doubts about installing the intake (read a lot on the pros and cons and potential warranty concerns). After some debating, I installed it last weekend. The fit was fine; there is one mounting bolt close to firewall that was a little challenging to get to install. Installation went well overall. I can't comment on any HP increases, its only been a week. I did notice a nice little rumbling note when you hit the gas - sounds good.
