Seafoam crap?!?
seafoaming the engine is actually really good for it. i just did mine like last weekend, and yes alot of **** came out of the exhaust, just like it's supposed to. it cleans your engine and sends the bad **** out of your exhaust. even if your plugs are fouled, they arent hard to replace. couple of hours tops, if you've never done em before.
