How come you did it twice
Took me 6hours to get the new one on and fit the plenum spacer altho did have a few problems with hard to reach bolts, i.e. the ones at the back of the cam cover also had to remove the coolant hoses to the throttle body as I didnt have the space to remove the cam cover when the upper plenum is sat at the side, only problem was I fitted everything then tryed to get the hose back on, couldnt get the clamp clip back on the hose and over the downward pointing pipe. That part alone took 30mins lol.
