Spark plugs
After I purchased my Disco, I first replaced all spark plugs since I thought that perhaps these hadn't been replaced yet. (The workshop record book was empty).
Autozone sold me Champion RC12PYP (double platinum) spark plugs. No real problems. The Disco had RC11PYPB4's installed. Does anybody know if that is a suitable Champion model for the D II ?
Also, when I pulled the first spark plug out, I wasn't sure what I saw, as I have never seen these types before with the tiny electrode. I thought that this spark plug was well over due. Perhaps not. It may have only needed the gaps set properly.
