I've got a question.... since you dont really have a whole lot of work done to your car what makes you want a A/F yes it looks cool and i want one too and i mean it will tell you your A/F but i mean it shoudnt really be too off, from stock dont you just have a cat back and CAI?
and lol why would you want the shift light built in to the A/F ratio you, my opinion, i would want the shift light near something i am always looking at, like for your car i know they make some good looking steering column mounts, or just get a nice little LED one you can hide.
