Speaking of sparkplugs. I've tried Googling the Champion, Bosch, etc. part numbers which are listed on Ebay.de for the 2 stroker Trabbi but so far have yet to find a spark plug here in the United States I can buy at one of the local autopart chains. I entered the part numbers on Advance Auto's website and it shows up nothing. I know I'm not going to find an Isolater spark plug at Advance Auto but looks like I could find something that would interchange. Any ideas? Otherwise I'm keeping the used ones that came with my car in my toolbox in case they ever foul out and I need to do a quick plug change on the side of the road for some reason.
