OEM Plenum / Intake Manifold Bolt Sizes - VQ35DE
There are a bunch of threads on here asking for the sizes of the OEM plenum nuts & bolts. There's some info in the FSM, but, surprisingly, even Nissan's fast system doesn't have the complete specs. Anyway, the OEM sizes are below - add 8-10mm if you're running a 5/16" plenum spacer.
Intake Manifold Collector (Upper) http://www.five-fifths.com/skyline/upperIMC.jpg Bolts 1, 3, 6, & 9 = M6 x 1 x 60mm (red) Bolts 2, 4, & 5 = M6 x 1 x 45mm (yellow) Bolts 7, 8, 10, 11, 13 - 16, & 18 = M6 x 1 x 25mm (green) Nuts 12 & 17 = M6 (green; these nuts & studs are sometimes replaced with M6 x 1 x 25mm bolts in aftermarket applications) Intake Manifold Collector (Lower) http://www.five-fifths.com/skyline/lowerIMC.jpg Bolts 1-6 = M6 x 1 x 70mm (blue) Nuts 7 & 8 = M6 (violet) hopefully this helps someone who wants to go back to stock, but has misplaced their OEM bolts. |
Well this thread is awesome. My brother broke one of my bolts that are supposed to be torqued in Inch-Pounds (The blue bolts) and we needed to find replacements. Thanks!

I found them at Lowe's near me. They are pretty organized and have a drawer in the hardware section specifically for M6 bolts. I found all the sizes I needed in there.

glad it helped :) :thumbup:
