What size TB possible with K&N FIPK?

mutabi · April 27th, 2008, 02:31 PM

Hey guys, I have a K&N FIPK cold air intake on my 02GT (57-2519-3 - K&N 57 Series FIPK, Performance Intake Kit). I am looking to upgrade the throttle body/plenum, and am wondering what size throttle body I can upgrade to, if I can do it at all. According to K&N they dont support after market throttle bodies.

Anyone on here running the same intake with an aftermarket TB? If so what size :-) I would hate to upgrade to a 70mm only to find out I have to buy another cold air intake.

I tried doing a search for this in the forums, but it seems like the search tool really hates the term "k&n" :-)
Any help would be much appreciated. Thanks guys.

Wow that was a fast response. No tight squeese on the TB?

I would say it depends on what you want to do with the car. If you plan on going with a supercharger or turbo, I would say go with a 75mm. I had an Accufab 75mm t/b and plenum with a JLT rai. I think if you really need to you could get a rubber boot that goes from the cai to the t/b from another speed shop or maybe lowes if need be.
