Review on High Performance K&N Cold Air Intake Kit for 2007-2009 Toyota FJ Cruiser, 4.0L V6, Improve Horsepower - Model 63-9030 by Oscar Colangelo

Installation took only about 30-40 minutes. with a knowledgeable buddy checking directions and fitting bolts through you can probably shave a few minutes off it. After installation I got about 2mpg and the sound in the cabin was a bit deeper and clearer. I didn't hear my truck from outside while driving. After adding the roof rack I lost everything but a small MPG boost, but that made up for it for me. Acceleration was noticeably better, especially at higher speeds on the freeway. The only bad thing I can say is that once the filter detached from the air intake and it seems like more rubber is needed to grip the tube. but now everything is in place, it only took a few minutes. and according to K&N it apparently won't pass CA SMOG but I haven't had any problems so far. I also added the picture above.
