Well the first problem we ran into while installing the 4" FWI was the massive coolant tank of the 1998 grand prix. I'd completely forgotten about how that gets in the way, and didn't want to wait for PFYC to ship the 99+ tank, so off to the junk yard loking for a 99+ GP. Just our luck that they have every car imaginable there, but only 2 GPs, one had an engine fire and was destroyed, and someone already took the engine out of the second! So we searched the junkyard looking for something that would fit, and eventually ripped a tank off some toyota and rigged it onto the gp, (yes, it's screwed on and secured, its not just sitting there). What do youguys think?
After that was finally out of the way, we cut into the the fenderwell and put the intake together. All that was left then was extending the wires on the air flow sensor and hooking up the PCM (which is just laying there now...but that seems to be what everyone on here does). This was probably the longest intake install ever because of the damn tank, but it was well worth it, it sounds amazing and it's running great.
