Very good plugs next to champion. I probably believe they're the best plugs I've ever put in my Harley Davidson.

Replaced Torch F5RTC

This replaced a Torch F5RTC spark plug for my Yardmax 20” mower with Honda motor. It requires a 13/16 deep socket spark plug wrench with arm attachment to get to it. I bought a socket wrench set for $20 at Walmart, too. Took 5 mins once I had all the parts.
