Anyone ported their aftermarket upper intake plenum? I know some guys at modular depot peaked 3 hp with the stock peice. Just wondering if anyone gained more with aftermarket plenums.

I don't think this is a real popular mod, unless someone wants to keep all their stock components on the car. After-market plenums with a larger TB will net 10 - 14 hp, though they cost about $400 to do both.

I dont think it would make any difference to port one of the aftermarket ones.
