OK thanks, but what if I want to clean the intake. Which hose that's connected to the intake can I suck up the seafoam with. PCV hose, EVAP hose, Air Assist Hose, Vaccum hose, etc.

use it through the PCV. Let it suck in slowly. Dont emerge the PCV down into the cup of seafoam otherwise you will flood your engine. Let the seafoam mist into the PCV (suckin air and seafoam at the same time).
All you need is 1/3 of a pint. It gained me 1 mpg or so on heavy city driving.

I put it in on my 2k GS400. I put it in my oil and got a lot of black stuff. I also put it in my PCV valve but got no smoke . Finally I mixed it with my gas. Got better throttle response and better mpg. Please make note that after searching I found that someone said you needed to change the spark plugs after sucking seafom through PCV valve. I did this and have had no signs of trouble for a month.

So, I did the seafoam treatment last night on my GS throught the PCV valve. Just popped out the PCV and sucked the seafoam up while mixing it with air as suggested. Turned off the engine. Waited 30 minutes, started engine, and opened the throttle. It smoked out of the tail pipe like crazy for about 3-4 miniutes. At a 165K it must have made a ton of carbon build up. Drove it around the block afterwards and it feels great, no problems. Some suggest getting a oil change right after because some of the carbon that is cleaned gets into the oil, so I'm changing the oil today. Thanks to those for their help!
