Upper intake fitting question...

[Fighting5thSVT]

I was wondering if I needed to do anything with the threads on any of the fittings that go on the upper intake ( power brake hose fitting, IAT, etc.)?? Do I need to thread lock or tape any of them, or just tighten them up and be done with it? I checked the manual and didn't find anything...

Thanks in advance!

I didn't put anything on mine, I don't have any problems. I did on the front fitting on the lower intake cause coolant flows through it. And the fitting for the heater hose.

If you don't have emissions, I would plug the EGR passage:

"3/8 X 18 NPT brass plug to be staked in place to prevent exhaust gas from ever entering upper intake."
