Used intake scoop in black (wanted the stealth look). Fits both 06-08 M and non-M (n52) models. I was skeptical till I saw the
dyno, 3.0si showed +6whp without altering factory tune. M models saw even higher gains.
I will be the first to admit though
$129 retail is steep for this piece, so letting it go for $75 shipped to 48 states. I have the 3 screws though you may want to run to your local hardware store and grab new ones.
Check my iTrader feedback, PM if interested. First to PayPal (as gift else add 3%) gets it.
