How to seafoam?

I didn't and do not plan to.

Every person I have talked to about sea foam (who knows about sea foam) are adamant about changing the spark plugs after this is done. I hear the the burning of this chemical can tarnish the plugs and shorten their life.

I am, but only because the timing is going to work out as both activities are due (seafoam, then plug change).

I just seafoamed my intake manifold after 100100 miles (I've got 7oz in the oil and about 8 in the gas). It took me about 2-3 minutes to feather all 10oz into the PCV line without killing the engine. I let it sit for about 15 minutes, then . . . let's just say I vapor-bombed I-25 between mm181 and mm183.

The butt-dyno says it *might* be a bit peppier, but it's really hard to say. It's not as much of a change as when I did the MAF clean and HCF delete at 95K miles. Worst-case scenario, I just spent $9.
