2.5 Plenum and runners
HI all, never seen inside a 2.5 plenum before today, and I was surprised to see that the intake runners protrude a 1/4 of an inch into the plenum air space itself! Obviously its supposed to be like this, however, would there be any I'll effect from grinding them back level with the bottom of the plenum?? surely the stock configuration constitutes a restriction to air flow?!
