Hello everyone, I'm looking for some advice on the 90mm FAST intake. My GTO is pretty much stock, with the exception of the magnaflow catback that was on the car when I purchased it.

I'd like to get the 90mm fast system and also want the k&N intake to finish it off.
Now for the question, Do i need to purchase a different k&N system if i'm using the FAST intake or is the FIPK still going to fit?

In other words, is the outside diameter of the FAST TB the same as the stock TB?

and second, what kind of HP gains would i be looking at for the full FAST + k&N system?? anyone have any experience with that?

Thanks in advance!
