Sorry to ask such a basic question, but does anyone know the thread dimensions
for the plugs that Mazda uses in the 13b, I'm looking to make an adapter for a
Fluke PV350 pressure transducer for a compression tester. Combined with a peak
hold meter it would make a great tool for the shop. Thanks, C. Smith Dang! My
thread gage is out at the hangar. Cut up an old spark plug for the base. Recycle :)
Anybody have any old spark plugs they can send to C. Smith? Paul Lamar I'll
re-imburse postage. Craig Smith 1754 Peavy Rd. Howell, MI 48843


what is the threads on the sensor? 1/8-27 pipe?
