Right now it has the gapless NGK BUHW in it but i believe they are fouled they are pretty old. I what to replace them what is the best kind of plug to use.
Clams says that they can be cleaned... I just did the Seafoam decarb by running from a 1 galon container of seafoam/gas. Can I clean them now, or replace them because I don't have many hours on them. Thanks,
