Don't bother with it.

There is no change in performance or gas mileage. I think it might have even lost a pep off the line. It sounds cool and that is about it. The directions were a little tricky. I had to keep looking at the parts diagram to figure out what hardware went were. None of the bolts, nuts, washer were labeled so you just had to figure it out. There was a problem with installing the air box bracket that attaches to the frame. I had to omit the lock washer just to get the bolt to catch and screw in.
Must have !!!!

I'm just starting to mess with my car and this couldn't be a better starting point. Instant gratification (after you install it that is). Boost in torque is easily apparent. Not to mention I went from 26 average mpg to 29.5 !!! A must buy.
