Always win when you use Champion spark plugs.

Bought for my 15hp Johnson outboard motor. Wouldn't use anything other than Champion forks, never have and never will use anything else. The performance you expect and get in every pack of Champion spark plugs.

Pros
  • Spark plugs
Cons
  • Minor repair
