I was at Summit Point Saturday and I noticed the squishy rubber covers next to the valve covers and wanted to remove them because they just seem like engine bay fluff, that and the rubber under the intake. I was wondering though if anyone has noticed lower engine bay temps after driving with the rubber removed. I feel like it would hold some heat in the engine bay and on the engine. Anyone know why Ford put that crap on there? Does it serve any purpose or is it just dress-up.

 

i beleive it was to keep injector noise down as well

 

That would make sense also.

 

Noise isolators.

 

That being said I think I will go ahead and remove them, I would not mind the extra noise and I feel like they hold some heat in which I don't want.

Having Autocrossed mine several times and ran a track day, the engine temp has never went above the middle of the gage even when idling for a time to enable the Trackey in hot weather.

 

You need to removed the strut brace and intake manifold in order to remove the two piece insulator. It's not hard to do and the good thing is you don't need to buy a gasket as it's re-usable.

I wonder if it is just possible to cut through the intake insulator or would I end up cutting a coolant hose?

 

You don't have to remove the intake manifold. Each insulator is held in place by 10mm nuts and come out easily once the strut brace is removed.

 

However I believe you do to remove the intake manifold insulator. I didn't even remove the strut tower brace and was able to remove the covers, since they were rubber I just wiggled and pulled till they came out.
