AC Delco makes the best air filter according to a study that is frequently posted on the forum in response to K&N filter questions.
I intend to switch to Royal Purple Syncromax in my nv3550 soon.
I'd stay away from the Seafoam. I had to replace both of my O2 sensors in my '97 immediately after using it. An expensive lesson. That could have gotten really expensive in my '01 where there are four O2 sensors.
There is a way to steam clean your engine using water. It involves SLOWLY pouring in water into the throttle body. I did this, and my engine runs even better than after the Seafoam, although it was a few months in between the two. After pouring the quantity of water in, I buttoned things up and drove around at 4,000 RPM to dry things out, and expel whatever crud had come loose. Jerry should be along shortly to explain things better than I have.
