Default New plenum

Here's that finned plenum thing. Can't wait to see the before and afters. I was going to post it in my other thread, but apparently the search function on this site says no such topic exists.

Man that thing looks cool. Let us know what you think when its installed. Hey just wondering, do you have to get your car retuned if you go with a new plenum and bigger throttle body?

That looks cool. Looks like it will restrict a little, but increase velocity.Cant wait to see numbers for it.

well.. aparently it's really good for forced induction applications. they're going to do a before and after on the dyno. if it really is better, they're leaving it on, otherwise, it's staying.
