Hey, im puttin my tpi back together, i wana know what should i put on the bolts when i put them back in..im talkin about the bolts to the runners to the intake and runners to the plenum.. should i put on some threadlock... what kind fellas.. i know this is a quick question that someone can answer this really quick for me.. thanks fellas

I just stick them in dry.

Never seez, or some similar type of material. Whenever you're putting steel bolts into aluminum, you want to use never seez. With those 2 metals, you get a corrosion that will fuse them together and make it nearly impossible to remove (unless you're like me and don't have anything assembled for more than a few months at a time ). This is why you see so many broken thermostat bolts in aluminum intakes.

In my case, I have stainless hardware, but it's still necessary to use never seez so that the threads don't gall.

I agree you need some type of anti seez on the threads of the bolts. You can find it at any auto parts store.

yea i know, i work at one!... thanks for the info... should i get the stainless ones that are on ebay? they will look good and will work well with my polished plenum shouldnt they?...

I like how they look, but the allen heads strip easily and they aren't as strong as steel bolts. They still allow you to tighten it sufficiently though.

The cap head stainless ones aren't too bad for strength. I had a set of the button head ones, and they were total junk, just not enough depth in the head to engage well. I'm lucky i got a few of them out.

Tip o' the day. Runner bolt installation is hella easier if you get or make a ball head allen socket. I also like to use a 1/4 drive ratchet to keep me from getting torque happy on 'em as well, a real plus with the stainless bolts especially.

Ed's right... the cap heads are a LOT stronger.

Of course, mine are button head. They do look nice all polished up though.
