Great for Sea DOo
Bought a used Sea Doo from dealer who was supposed to have tuned it up and changed oil. Suspect that he did neither, based on the performance on the first test ride. Spit, sputter and run about 1/2 speed. Treated the used gas. changed the oil and changed all three plugs and now runs great as it should. Dealer thru in a new battery only because his mechanics forgot to charge the old one when they loaded it on the trailer prior to my arrival. Once he had them change it, she started and idled fine. Didn't find the rough running until I took it to the lake. You can always trust NGK for a good spark.
