Cold Air Induction kits?
How many of you guys have replaced the air inlet plumbing with higher/better flowing CAI's? What were your thoughts about gains vs cost?
I've been thinking about adding one to our 2003 Boxster S. I'd like to get some input from actual users before I drop $700.00 + I know power gains are relative to the amount of power the engine produces before mods, I just don't want to spend poorly.
Thanks
Don
