I'm a bit surprised that neither of two major Healey suppliers specifically identify the plugs they sell for Healeys, in my case, I believe, the stock 29D engine with electronic ignition. The search function pulls up a few suggestions for the BJ8 and every other Brit car found on this site. Suggestions? Also, I notice that I am identified as a Jag MK 2 and a Porsche 968. The Jag is now happy in Maine, the Porsche is in the driveway, and my portion of the garage holds the '60 BN7 that prompted this inquiry.
