ive heard some people say that after installing a new intake, you need to go back and re torque the lower intake bolts once youve run the engine. the only problem i see here is that the lower manifold bolts are next to impossible to get to once the upper plenum, fuel rails, wiring harness ect are on. is it really necessary to take all that stuff off again just to re torque those lower bolts? anybody have experience with this? blue loctite maybe???
