I'm in the process of finishing up my build and found out that a lot of people use a gasket on each side of the thermal spacer. How many people have this installed without any gasket or copper spray like map suggested on their website

as long as the spacer is perfectly flat you should be ok, but if its not i would just use two gaskets like it suggests on maps site. it also says you can use copper spray directly on the spacer.

as long as its flat it will seal though. if i was going to use that, i would personally just use the two gaskets to avoid any leaks since the intake manifold is such a pain to install and remove.

 

great price on that gasket.

 

I have it and used copper spray and 2 gaskets no issues just had to re-tighten the bolts after a few months

 

I have the same spacer.

I used no gaskets or spray and actually just reused it.

boost leak tested to 40 psi with no issues

 

i also run this spacer. no sprays or gaskets. i have removed my manifold more times then i can remember. just make sure each mani bolt is TRQed properly. you should be fine.

 

Thanks for the input guys, I'll do a boost leak test and see if it holds.

 

i have the map spacer with their rev3 manifold. had leaks out the a$$ and had to use the two oem gaskets. also having a problem with a mil spec tb im trying to sort out now.
