World’s Best Aviation Spark Plugs!

Last year we had the fewest plug related issues with the B-17 that I can ever remember in 25 years.  Tempest plugs really made a difference in the day to day reliability of the EAA B-17 “Aluminum Overcast”.

I swapped out my old Champions for a set of Tempest Fine wires in my Navion with an IO-470H. The engine runs like a scalded dog. It will idle down to 700 RPM with ease. I took a friend flying and when​ we landed he said, “Don’t shut it down, let it Cadillac for a few minutes.”

To the guys who make these things, your work is appreciated.
