through the vacuum line into the intake closest to the grill.. it was pretty smokey while sucking it up but nothing during the idol or after letting it sit for twenty minutes... don't really notice much of a difference at all either... used half of the big bottle... twas fun though i liked the little bit of smoke that did come out

you only had a little bit of smoke? That's weird because everybody else that has done this before including myself have had alot of smoke. what year is your car?

i am about to do a seafoam to my car. can some one find me the diy or a link to more info on it. i dont really know to much about it

its a 99... i didn't let it sit for too long though, i wasn't really watching the time but i think maybe 5-10 minutes before firing it up again... and i'll find the DIY hang on...

MAn everytime I turn around my mom is adding that seafoam to something or someones car-next she will be putting it in the lawnmower!!!! (seafoam un-inthusiast)
