WARP TEN · 01-17-2013

I was down at Marc's place the Tuesday looking at my engine--whose pieces were scattered around various places in his shop--and he showed me the plugs. They were the original AC 907s (car has about 20k miles on it). They were actually in pretty good condition and the engine certainly ran fine. But one was missing the platinum wafer on the electrode so we are replacing the lot. I think with the NGKs but I can't recall precisely. I remember losing the platinum discs was a problem on my 93's 907s which also went by the wayside. --Bob
