If I were you, I would suggest going for the K&N. I, for instance, have a Cosworth, but it would take at least the cost of a new CAI to get me to sell it. I have a smog check coming up soon, so I need the CARB sticker. I hope to no longer be in California when the next check comes around (can someone say FI?).
