Seafoam is a solvent that you use to clean built up carbon and other deposit crap in your engine. The dealer will do this same type of procedure but will call it "induction" clean. You can put the stuff in your gas, crank-case, and directly inside your block via brake-booster. I will tell you I did it every ~25k on my old lexus and it really does work! Idled and ran sooo much smoother after.
To the OP, I recently acquired my 4runner so I do not have any input to add yet as far as where to put it in but I found this link which will probably help:

Not looking for your opinion, just the place to introduce the seafoam into the intake.
The sucker hose.

Thanks for the recap big webb but I wasn't asking where it was, this isn't my thread. I found the answer from going through the link provided by Snesley Wipes. I just think it is crappy for people to act like an ass when someone is asking a logical question. Much like how you bring up me "kicking you when you were down" in a totally unrelated post where you still don't get it even after multiple people tried to explain it to you...get over it and move on...I have...even the moderators deleted your thread.

You may be aware of this already, but I'll throw out this thought for whatever its worth
Several times in the past, when using Seafoam, you could really see the results but -sometimes- it fouls the sparkplugs
If anyone else tries this for the first time- consider checking your sparkplus or have a set standing by if you are using seafoam as part of a complete tune-up

I love Seafoam! Might have to do with me being a Rotorhead... lol But the stuff works well enough to warrant use here and there. In reality you just need a vaccum line into the intake maifold, I ussually use the PCV Valve Hose as its big, easy to get to (on most vehicles), but on the 4.7L it happens to be easy to find.
Your PCV Valve is located on the valve cover to the left of the oil filler tube, its a large foam covered hose, just pop it off and use that. Another option is using the long hose that is off the top nipple of the intake manifold (its the only vaccum line on top of the manifold, hard to miss), just follow it to the lil solenoid ontop of the P/S disconect it and use that. (remember to reconnect it when you are done and before driving off.)
Big thing to remember (I figure you already know but I wanted to state it for everyone) when using Seafoam or any other fuel injector cleaner via a vaccum line you will need to manually accelerate the vehicle to a high idle or at least another thousand rpm. Don't be afraid to rev it high some because you don't want to stall the engine and flood it. (Though there is a method of using Seafoam that you intentionally flood the engine, but the OP is not using that method) I also reccomend some spirited driving afterwords (and yes by spirited driving I mean drag race that bad boy!) to burn off the excess. I like to use about have the bottle in the vaccum line and the other half in the gas tank.
Okay I think I've rambled on long enough. VIVA LA SEAFOAM!

You shouldn't have to worry too much about plug fouling, the Seafoam is designed to burn pretty well and your ECM will be cutting fuel to the cylinders because it will think it is providing too much fuel. Honestly the only thing that would really hurt the engine/vehicle would be if the Seafoam unstuck some chunks of carbon and it plugged up the Catalytic Converter but the chances of that happening are very very slim.

i thought the seafoam u just put in your gas tank??

Not too high a fan of dumping it in the oil, but that's how to use it. Another way for really heavy carbon is to purposely flood the engine with Seafoam and let it sit over night. Then unflood the engine and drive it hard.
After watching videos on seafoam and seeing people completely fog out the neighborhood I figured I'd give it a go. So I bought a can of seafoam and drove to an empty parking lot to try it out.
I pulled the vaccuum line shown in the photo, it had suction and was going into the intake so I figured it would be OK.
I followed the directions on the bottle, 1/2 in the throttle body, 1/2 in the gas tank.
RESULTS: Not even 1 puff of smoke, no difference in drive quality. Maybe I did something wrong IDK. Seeing as my 4runner has 90k miles I figured I'd at least get a little bit of smoke but nothing. It did idle down a little bit when I added the Seafoam for about 10 seconds but other than that nothing happened.
I'm on my 2nd tank of gas now so my gas tank should be pretty much clear of the Seafoam by now.
