Can anyone tell me what the best way to wrap the coil packs is? using aluminum foil how far down do i go? cover the top and all the way down till the red rubber tip? Is there a downside to doing this?

 

I would not use aluminum foil! if you are trying to protect them from heat you should google "thermal blanket" and pick up some of that. works great.. I put 3 layer between intake manifold and the valve cover, and I wrapped my header with it.

You could just cut a few peice and cover the tops of the coil packs.

 

Same here! thermal blanket is the best!!!

 

already done that and removed it. Actually rose the intake air temperature with it on. Why no aluminum foil?

 

Leave the foil for the kitchen....I cant believe thermal wrap didnt work??

 

What kind of IAT readings are most people getting.
