Might have something to do with the ports too......
 

and did you forget the melting heads?

APRs bipipe fails waterpumps and timing belts?? Proof?

i am talking about where the intake runners from the manifold meet the heads

Nope I would rather have the lower C/R than the huge ports.

He's talking about the intake ports of the head. Without porting them
 

you'll just have a nice big step between the rs4 intake manifold and the s4 heads.

Damn, you beat me by a minute! ;)

That's IF it's not properly installed...and ther have been allot of reports lately about it.
 

I asked a buddy about his installation and he told be that he had 1/16 inch clearance to his fan blades.....personally, I'd like to see a little more clearance.

Get the RS4 pipes 8^)

I thought the RS4 intake manifold only bolts up to the RS4 throttle body?

it does
