Phenolic Spacer Kit - C32/SL32 AMG $149. V8 Shown below.

Detailed DescriptionDesigned and developed by evosport, these intake manifold spacers help reduce intake temperatures by as much as 100 deg F. Perfect upgrade for a supercharged vehicle where heat is your enemy. Install in about an hour and include factory replacement intake manifold gaskets.

 

I don't think anyone over here has tried them yet.
Some MBWorld guys have and some SRT8 guys (a different brand) have w/good results.

 

Hmm... I'm tempted as there is a lot of heat issues around there and anything that helps will only be a good thing. It's not as if they are expensive either. I just wonder how easy the fitment is.

 

I may try them eventually. I have read that the machining on these is not that great, but I haven't heard of any issues.
The install should not be that bad.
I think NeverEnough may put them on his as well.

 

I have them. They're not too bad, they do cool down the intake manifolds quite a bit, but I have no numbers to give any quantifiable differences since our IAT sensor is located in the Y-pipe before the manifolds. I did a 150+ mph run and then pulled over and touched them, they were still hot but not too hot to touch them like before.

The only issue is it does not cover all of the bolts and some people have over tightened the ones that it does not cover, and this breaks the seal. It's hard to explain without pictures... I'm going to take apart my supercharger in the next few days and ceramic coat my intercooler, so while everything's off (or while i'm taking everything off) I'll post better pictures and then explain what I mean. The picture above doesn't have the same issue ours has, or I could just show you on that one.

 

I plan on putting them in along with the NeedsWings Cold Air Intake as my rest round of mods.

 

Great. Looking forward to them.
