I was thinking about buying the 2002 TL Type-S upper intake manifold for my non s tl. would it fit? and if it does, would the car even run? would there be any performance difference?

 

Yes, it will fit and yes it will run...However, before you spend the money on that, you might as well get the 09 manifold, which is a little bit larger...The torque gains are apparently quite noticeable...
A few guys on here have done it already...

You will need to get a throttle body adapter from p2r for it to work, I believe.

 

from what i understand the 09IM is smaller and lighter, but yields higher gains.

 

awesome, i'll try that. and where do i get the adapter? i dont know much lol

 

From P2R

 

Id use the 09 IM and id suggest getting used to the search button. Most things can be answered quickly with it.

 

its not smaller, just shorter and its made out of a lighter material

 

haha that's what i meant, better for hood clearance.

 

I don't see it suggested above, but you should also get a type-S throttle body as well. It would be a shame to get a better IM and still use a TL-P TB.

 

09 manifold definately the way to go i feel alot more difference than my type s manifold

 

looking to do this real soon
