I was looking at the plugs I pulled out of my 66' 140 tonight. I noticed (4) of them are Bosch W8AP, and (2) of them are W8AC. I assume the W8AC's are AC plugs but the markings on the ceramic can't be read. What are the best plugs for the 140? Scott Ham hamitup@earthlink.net Why Wait? Move to EarthLink.
