Intake horn bolt torque

[kblranch]

Just installed a GDP intake horn and need the torque specs for the four mountlng bolts. Thanks in advance.

Service Manual states 18 ft-lbs on page 14-91. However, I would start at 10 ft-lbs and probably go no higher than 15 ft-lbs. Those are small diameter bolts...

18 ft lbs is normal for an 8 mm shank bolt. Follow the factory specs. I would recheck them after a few heat and cool down cycles

Thanks for the replies

Just a useless FYI... 8mm is the equivalent to 5/16"
