i have read some people have had good performance when using a t2 intake on the 6-port, i am not looking for the 3-5 hp gain, but will that intake raise the rpm powerband? if the stock s4 intake is rated at 6500 peak hp, would the t2

raise it to 7500 rpm? possibly?

 

t2 is about 5500... although that's with the turbo.



seems like a ton of work, and there are few gains if any. seems like for a 6 port the best stock intake is the 89-91 one. with the 6pi and vdi working its tuned lower and higher than the s4 intake
