I know K&N makes a whole cold air intake, but I wonder if it really improves anything that much? I mean, I'm not going to spend $250 on something for a 1 or 2 percent increase in acceleration or power... but it it's like 15 or 20 percent, I'm all ears...

I know that it is always a combo of stuff that makes the difference - I think I saw bigger headers for this engine too... but then, I'd have to redo the whole exhaust - Too Lazy, and it is fine right now...

I would love to be able to mod the OBDII - or at least let me see what it's doing in real time.... without spending a million dollars...
