Review on Autolite Copper Resistor Spark Plug by Justin Abreu

Revainrating 1 out of 5

NOT for Small Engines

Spark Plug 386 IS AN EXCELLENT SPARK PLUG BUT THE THREAD SIZE IS VERY LARGE AND WILL NOT FIT ANY KNOWN SMALL ENGINE. I HAVE USED THEM ON FORD AND CONTINENTAL (RED SEAL) ENGINES.

Pros
  • Automotive
Cons
  • Operating Speed
