I'm sorely tempted to buy one of these for my Celi (it's Australian, but equivalent to 2004 GTS).
The only mod so far is to remove the butterfly on the CAI
(lame, I know) and I'm pleased with the induction note...
Can anybody relate their experience with the Apexi S-AFC II so I can make a (slightly) more informed decision to buy it or not?
The other choice is a turbo kit, but that costs about twenty times as much and I'd have to think even harder before spending that!
