I have a MAC fenderwell kit.
Changes:
- Increased fuel consumption "due to increased air flow
- A nice hollow-sucking-deep-tone when i hit 3 grand, but you really have to know your car to pin point it.
Was it faster? I can't tell. For $250 canadian ($25 US), i think it's a little steep for such little gains.
If were to do over again, i'd put my money towards gears or an H-pipe instead.
V-8's don't respond as well to filter charger kits as do the 4 cylinder engines.
