That MMR intake is for race applications isn't it, and i know it's like 2 grand or more for it. Like mentioned, you need to be pushing some serious power and FAST is making an intake for our cars but not sure when it's coming out, maybe soon.
If you car is stock, i would get a good CAI and tuner first. I wouldn't really worry about the throttle body till you get alot more bolt ons.
As far as the manifold goes, I am planing on some serious HP ... right now im gathering info. the 1st thing on my list is an exhaust. then from there i will pick my next upgrade. Right now, i am disecting my car and looking into upgrading as much as possible.
but like i said, i dont know much about cars, but i am learning as i go along.
I have heard that sheet metal manifolds are not good for street applications.
++++1 on the throttle body and spacer being a waste of money. I am pushing 544rwhp and still have the stock one in. The BBK only seems to cause issues and the stock one seems to be a great match for the stock manifold.
Start by telling us what your goals are for your car. If you want a 800hp monster or a 420 hp street car.
Just remember to these Rods in the stock motor only can handle 450hp give or take.
While you're wasting money on TB spacers and manifolds that won't fit the average joe's purpose, I got some good swamp land out here in San Diego for sale. Comes complete with ketchup popsicles and a unicorn too. :nogrinner
