do you need the peice that goes on the bottom of a throttle body for an lt1 or tpi. i accidently sold it with some other stuff and now im without one.

Yes!!!!!!!!!!!!!

lol im an idiot.. i see why now that i look closer... you ever post somthing then find out how stupid you were for posting it??lol.. i guess i didnt see the port that goes into the tb i was thinking i could just bypass the antifreeze and be good.... looks like a big NO

i baypassed the antifreeze part and ground it off but the other part holds the iac (idle air control) valve. and you do need it.

Yes, I ususally get a 'Bad Devil' from the penut gallery too.
Don't sweat it, someone someday will find this and it may help them (if they learn to use the function).

Oh yea, yes you need it.
