These kits are made just for the 3.2 VR6 or the 2.8 24Valve VR6, and the 12V 2.8L Included is 1 head flange designed for either (yes they are different). 1 plenum plate, 3 U-bends (You cut in half to make 6 runners), 1 Throttle Body flange (for engine of choice) and 1 4-port vacuum flange.      

Create your own design on the plenum to fit your needs. Some like to do a box style, some like the pipe style. Plenum plate is rounded at a 4” diameter on a 3.5” wide plate. This lets you use from 3.5” or 4” elbows with minimal work. (4” for larger planum volume).
