Exclamation 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. The OEM sizes are below - add 8-10mm if you're running a 5/16" plenum spacer.

Intake Manifold Collector (Upper)



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)



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.

You can also; from these diagrams, calculate the extended bolts needed for any size spacer.

I've just been wondering about this, thought I'd have to pull each one out and match it. I guess like Sean says I can just add 8mm (approx 5/16) for my MD spacer.

Thanks a million, Chris!

I just picked up a used MD spacer, with no bolts. What's a good substitute for the 6 plastic spacers in the middle (bolts 1 -6)?
