My oem intake hose broke on my 84 Z31 NA and couldn't find a replacement that wasn't old/used so I took a chance on ordering a new one that's meant for a Pathfinder/Frontier/Xterra.
They're only slightly bigger than the ones on a Z31 but tightening the clamps sealed everything up, took my car for a 10 minute drive, and no air leaks.
The only thing I don't like too much is that the upper hose kind of goes past the plastic line but it works. You can probably cut the ends off of both sides for a better fit.
The part is from Dorman part # 696-009.
