I can find a bunch of threads for installing a plenum spacer, but I need to remove one and haven't come across any after searching.

I've got a car that came with a spacer, and that isn't legal for the class I'm running in Autocross.

Looking for any advice on removal? I don't have any of the OEM bolts, so I have to figure out what sizes to use, anyone been through this process and documented it before?

TIA,
Chris

 

Remove intake manifold, remove spacers, replace bolts


What is there to need help with?

 

Heh, I guess I could have been more clear on that.

Mainly it's the replace bolts part, anyone got any idea on part numbers for the necessary bolts. Don't spacers come with new/longer bolts?

 

I would go to courtesy nissan and just order all the bolts, or if you want to save some money go to pick and pull and grab a set. There was an engine dress up thread with bolt lengths, can't seem to find it tonight but all the bolts are m6x1.0 thread.

 

Be careful removing all bolts. Go very slowly, use the proper sized wrenches (1/2 drive), use a torque wrench when reinstalling. You will hate life if you snap a bolt.

Get the FSM.

 

This thread has all the bolts listed, which is ultimately what I needed, should be performing this later in teh week.
