Terrible Spark Plug - Waste of Money

Based on our own experience, this spark plug was a complete letdown. It failed to ignite and caused our engine to consistently misfire. The only good thing we can say is that it was easy to install. Unfortunately, its poor performance makes it a waste of money. We do not recommend this spark plug.

Pros
  • High quality spark plug for Cummins engines.
Cons
  • Requires specific knowledge and tools for replacement.

Could have saved half my money and just bought

NGK spark plugs Should have just bought an NGK spark plug because that's what it is. I could save half my money. This is an NGK spark plug in Cummins packaging only.

Made for my Onan Generator model.

Thanks to investing in a motor home. I want it to be serviced regularly with the best OEM products available. RV generators don't come cheap, so don't skimp on quality replacement parts for more than a few dollars. Using counterfeits may void the warranty. This spark plug is recommended by generator manufacturer Onan. I'm calmer! The plug was installed correctly right out of the box.

Pros
  • Automotive
Cons
  • A few little things
