So i lost this little nylon washer for the lower plenum. called nissan, they dont have it, there is no part number for it, and it doesnt come with the bolt. it doesnt exist according to nissan. can anyone help me get a hold of one? or any ideas?

 

i may have one since I replaced my lower plenum with my cosworth intake.


Let me check my garage...

 

found my lower plenum bag of bolts..no plastic washers. Didnt see them on courtesyparts.com either...



are you the original owner? Stock intake manifold? That spacer looks like it was for an intake spacer ( given the length of that bolt next to it, the bolt looks like 1 of the 6 holding the upper plenum to the lower plenum)

 

I'm not the original owner. It came with a plenum spacer. So maybe that's what those are for...

 

so you took out the plenum spacer? then you dont need that spacer/washer in there

did you lose it down the manifold? i suggest you get it

 

Unless you lost it down the manifold, then I wouldn't worry about it. None of my bolts have washers on them and my car runs perfectly fine (well..."fine" being "factory")

 

I lost it in the engine bay. I'm just gonna get rid of the spacer. So that I don't need those things. Glad its nothing important. Thanks for helping me figure it out everyone

 

uh, spacer = good,
Dunno. up to you mang.

 

Just take a washer from another bolt down to the hardware store and pick one up. The spacer is good upgrade.

 

Oh the difference is spacer vs no spacer? I'm with them and I vote for the spacer; it adds some decent power for a bolt-on
