For those of you that replaced your plenums, did you bother to use the proper torque settings on the plenum bolts (5) or just guess. I replaced my stock plenum with an Accufab and my manual recommeds the following torque settings on the plenum bolts:

53 inch pounds
then
71 inch pounds
then
90 degree turn

My torque wrench starts at 120 inch pounds[:@]

 

I think its supposed to be between 71 and 106 inch pounds. I did mine by hand with no problems. Just dont go too tight, you don't want to crack the plastic manifold.

 

Just use ur best judgement.No reason tobe a hero and crack ur manifold like Mark99gt said. Re-check them in a day or two to make sure they hold tight.
