i would go with the brake booster line since it will reach the entire engine and is easy to locate and use.

so the brake booster cable WILL in fact allow the seafoam to reach the ENTIRE engine?

upppp

so i seafoamed the 2008 G35 yesterday using the main brake booster vacuum line... put 1/3 of the can in there and let it sit for about 30min before i started up the car. it smoked, but didnt smoke as much as my 2004 350z with the same mileage (and the 350z was properly maintained, using 91 gas only, and 95% highway driven). makes me wonder if the seafoam through the brake booster line only went to 1/2 of the engine on the G...

It's a 2008... I still don't get why you bothered with this.

I am pretty certain it went to your entire engine since it goes through the plenum

60k
87 gas since day one

^ ouch, I dont think I would ever run 87 on a G35 :(

i wouldn't be surprised if most g35 owners ran 87 :icon43:

93oct here. Not even 91. If I could run higher I would.

93 all her life!

Anyone tried half race gas mix in the tank? 93 + 100 ~ 96/97oct

Seafoam is an Engine Cleaner that gets rid of deposits in your engine. It is usually done for cars that have high mileage. Someone before used Seafoam because he had rough engine idle and it fixed his problem. I would not recommend using seafoam on a car with lower mileages because it is a risky process and your car will give out error codes. Only use Seafoam at your own risk or with a professional car mechanic. Google is your friend.
