(New Surplus) 18MM longreach, shielded, 3/4-20 barrel. FAA approved for Continental IO-470, GIO-470, TSIO-470, IO-520 and GTSIO-520.
Not for 0-470, which uses short reach plugs.
Very Good Item, good value and fast delivery.
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.
Very good plug
Yes, these plugs come with a copper spark plug gasket.
