While I refuse to believe that the HAI allows the car to make significantly more (or less, for that matter) power, it provides very similar performance at a fraction of the cost. Note that this may be different at the extreme end of the mod spectrum, which I have yet to test. My suspicion is that AFR is god in this arena.
After shipping, the ZZP box intake is what, $230? (how about the k&n recharge kit, too, since it's an oil filter? Those are like $15, raising it to $255.)
How about a $25 dry cone + $220 headers for $245? Who's making more power for the same dollar?
