Going by feel that seems like too much torque for these small bolts in the aluminum intake. are you sure this is for the "X" code motors? I saw those specs for the W and Z motors, but have nt been able to find a specific listing for the X motors which makes me wonder if they are different. I can't afford to strip these out or break them.
this is the correct specs for the x motor i have included the screen shot from my software you need to make sure you are using inch pounds not foot lbs
