Upper Plenum Bolts


Daily Driver
I need to know ASAP what size and length the stock 5 upper plenum to intake bolts were? :confused:

Installing my Race Jace plate and J. J. upper plenum and throttle body, but the bolts I took off were through my old Kenne-Bell plenum spacer and are way too long.

Couldn't find it in the manual either...

If memory serves correct, they are 8mm X 25mm. Don't forget to chase the threads before installation.
Well normally if they thread in and work I leave them. ;)

This time I actually went to Sears Hardware store and got the right ones, even 5mm longer to avoid messed up threads. :rolleyes:

M8 x 30mm standard thread. Expensive at $4 for 5.
