Title: KN Air Charger on '08 FJ
Review: Install only took about 30-40mins. with a literate buddy to check the directions and hand off screws to, you can probably cut it down a few minutes. after the instal I gained about 2mpg and the sound in the cab was a little deeper and more pronounced. i havnt heard my truck from the outside while driving. after i added a roof rack i lost all but a little of the MPG gains, but it evened it out for me. acceleration was noticably better, especially in the higher speeds while passing on the freeway.the only thing i have bad to say is that the filter came off the intake once, and it seems like it could use more rubber back there to grasp the tube. but its all situated now, just took a couple more minutes. and apparently it wont pass CA SMOG according to K&N;, but i havnt had a problem yet.i added a pic above also.
