Alex (or anyone),

Please post what you find. I am planning to add the plenum. These pictures and posts, and positive users' reports, are too much for me to resist.

But I am curious: Has the effectiveness of the plenum been proven one way or another by a third party? It seems to be such a simple test.

I think the majority of what difference you see on your car is probably the result of the exhaust which reduces 50% of the back-pressure.

I am very interested in the plenum upgrade but something just doesn't add up for me.

I will grill CG next week on this.



You have to follow your heart my friend. I think what I feel is the exhaust/plenum combo and with one of them only I would have not noticed as much difference as I do now.
