I was searching for the same thing and came accross a site called "torkspecs.com" they say 33 ft/lbs but I want to make sure myself since it is a Auminum intak.e. I hope this is help to you.
No more than 35 ft/lbs. To be very accurate with the torque, use a 3/8 drive torque wrench not a 1/2 drive. The 1/2 inch drive torque wrench is long and designed to torque bolts that are at least 1/2 inch in diameter and require at least 60 lbs of torque. The intake manifold bolts are 3/8th with a flange. If you lose a bolt be sure that you use only flanged bolts. A flange bolt is a bolt with a molded flat washer. In my experience in the trade of rebuilding engines, never use a 1/2 drive torque wrench to tighten bolts under a 1/2 inch in diameter. FYI the term (drive) is the size of the square part of the socket and socket wrench. Available in 1/4, 3/8, 1/2, 3/4 and ect.
44 in-lbs. step one. and 89 in-lbs. step two
under the intake manifold
step 1 is 44 inch-lbs step 2 is 89inch-lbs.
They are underneith the intake manifold. You can not see are get to them until you REMOVE the INTAKE manifold.
Under the intake manifold.
The intake manifold is bolted on the center of the engine between the 2 Valve covers.
It is inside the upper intake manifold.
