I have been using these plugs for over 2 years. Work great, but did have 1 that was DOA. I guess that would be expected considering they were made in 1960. At this price, I replace the plugs every annual instead of cleaning.

5 stars for easy ordering, and delivery as promised. We had some of these that had been here for maybe 25 years. Decided to use them. Normal life and performance, which is my main reason for ordering them. Glad they were in your catalog. Our IA recognizes them as a no problem plug.
