I have a typical Lycoming 0320 of 160 hp in my RV-4. It has one normal Slick magneto and one Electronic Ignition in place of the other mag. The electronic mag fires automotive spark plugs which are DENSO Iridium IK27 I have not had much luck in finding these plugs and was wondering if anyone else uses auto plugs and what brand and exact plug in their airplane. I am sure there must be a more common plug that I can use. Anybody got any suggestions.
