is it totally necessary to have the engine cool off for two hoursbefore installing a SRI? Or if i can touch it without burning myself, is that ood enough

 

wear some gloves, be careful and u should be alright. if u've driven around for a long time and want to get started asap, let it sit with the hood open and with a fan blowing on the side of the intake, after a few minutes the parts u need to touch should be cool.

 

I'd wait about half an hour
