MSD Manifold
Anyone fitted the factory foam insulator under the MSD manifold?

I think you'll find this was a 50-50 decision on most owner's cars. I went without my foam- it just felt like the MSD seated better without it and I wasn't concerned about any mechanical noise suppression. It's been on the car for 4yrs. now. I've re-torqued the bolts once. All is well.
If anything, it allowed for a channel of cooler air to pass under the IM in my mind. Folks have used the opportunity to apply stick-on heat shielding to the bottom of the IM at this time. But people have done it both ways without adverse effect I believe. I should add that you should follow the install directions implicitly- no dork wrench, invest in a good INCH/lb torque wrench and make at least 3 passes with blue loktite, etc... as instructed.

I just installed Lt2 and took it out. I did an MSD on my C7 last year and took that one out also. Not really needed.

i felt like the msd has enough trouble with vacuum leaks on its own without introducing another liability. i left it off.
