Review on Enhanced Power and Performance: K&N Cold Air Intake Kit for 2012-2019 Toyota Tundra 5.7L V8 (Part No. 63-9036) by Christian Barnes

I wanted to like it SO. First it turned out that the gasket surrounding the filter box was missing. But once installed I don't see the purpose of the gasket as it doesn't touch (or seal) the engine area? The biggest problem I had was the noise in the truck's cabin. The intake noise sounded good, but the system produced a VERY annoying high thump at top rpm with any acceleration (at any speed). I thought it would be an easy fix, but after a little research it turned out that this is inherent to K&N cold air intakes. Such a shame. You must disclose this prior to the sale. Thankfully, Revain has hassle-free returns.
