FRPP Coil covers

[JimInNY]

The heat's no big deal. Did 20 mile runs today (110 ambient temps) with no covers, stock covers, and aluminum covers. COIL temps averaged 191-197 in all 3 configurations. The FRPP units are here to stay and look even better to me after putting the stockers back on to do this test today.

So I can put my stock covers back on with the comfort of knowing that it makes no difference, with or without?

Thanks for doing to research! :)

I'd say so. If I only picked up a 5-10 degree difference when it was 110 outside (and I have longtubes so my underhood temps are elevated anyway) I'd think everybody else should be ok... Maybe bumper to bumper traffic or road racing would be worse but I'd say my "test" was pretty extreme.
