I only did the 3.2. What size is the 3.4 

I think standard is 74mm and most go to 82mm.
Was considering having an 82mm plenum fabricated if I cannot find another option.

The X51 kit, GT3 OE plastic plenum price sky rockets from £55 for a 74mm to nearly £700 for an 82mm which is insane as is the price of the IPD units. Porsche keeping us away from them and putting the 911's to shame, no doubt :-)

Mine was a 996 throttle body. Do you have a picture of yours.
