4 inch intake pipe?

[Jicaju]

For those running the bigger turbos which have the 4 inch inlets, does it require a spacer under the plenum to clear up pipe? I know it will require the angle IAC boss.
Thanks Michael

I run a precision plenum w/power plate and it clears the 4" pipe, its not a spacer but it is taller than stock.

I have a 6152S on its way. Im going to try the 4in pipe from the GN on it. The only problem i see is the area over by the fender..Have to get the car back from the paint shop tho..

Have one on my T and it clears, but still pretty close to the up pipe. I'm running a sheetmetal plenum with 3" up-pipe from the fmic. The 3" pipe made it a bit tighter, but it does fit.

Louie......I think you will like the GT6152S. That's what I have on my T and it pulls hard, even at moderate boost levels. I can't wait to crank it on up once I get a few miles on the new engine.

Good deal. I was hoping I could get away with the power plate. Clearence is pretty tight under the hood.
