seafoam

Would there be a benefit to spraying seafoam into the intake with a small spray bottle or even a larger one over using a vacumm intake?

The preferred method is to use some tubing and suck it into the intake with the engine running (and already hot). Turn it off, let it 'soak' a few minutes and go fog your neighborhood.

I recently tried this (using the spray can) and it was kinda a PITA. I gave up after about half the can. Given that, I'm guessing there was little to no advantage. I'll be sticking to the vacuum line from now on. I've been told 10 minutes is the appropriate soak time. Too long and it becomes less effective.

Isn't 'deep creep' an aerosol version of the same formula? I always thought it was, but I might be wrong. I still use the vaccuum line with the seafoam can, but it can be difficult finding the right line on random other cars.

The M3 has that big plentum intake over the ITB. I thought it might help distribute it to all ITB.

Does anyone know if "Seafoam" does any harm to the CAT? My worry is that there is a lot 'junk' going through the pipe to be burnt off.

More Smoke?

Pretty sure it is too volatile to be a risk to the cat, especially if you've warmed-up the car prior to the treatment. A cat that's up to temp should pretty much burn-off anything that doesn't get cooked in the combustion chamber, which the seafoam/carbon has to pass through first anyway.

The correct way that professional shops perform an induction clean service is by using a bottle with an IV style drip that connects the hose up to the intake as mentioned above. You let the car run for about 30-45 minutes with a slow steady drip not by overloading and soaking the intake then smogging out the neighborhood. I need to finish moving as I have one of these IV bottle kits from my previous job.

Although, letting it soak a bit may not be a bad idea for a small amount once if you've never done the service before.
