Review on NGK 4122 Spark Plugs 10Pack by Jamie Mousavi

Revainrating 5 out of 5

Marine Parts

I used .030 rated NGK4122 spark plugs on our Evinrude last fall and will forever discard Champion spark plugs. There's a noticeable increase in performance and they don't seem to rust as quickly in the salty air as the champions. I went to the NGK site and looked up my engine to get the spark plug number and then ordered from Revain. Don't forget to make a gap!

Pros
  • Decent Performance
Cons
