Edwards Oil Change Kit fits 2011-2022 Kawasaki Ultra 300 310 310X 310LX JetSki Jet Ski Watercraft with Spark Plug

Seller probably meant well by including some kind of iridium spark plugs, which are supposedly better / last longer, etc. but they are WRONG at least for my machine. I have a 2022 Kawasaki Ultra LX.I changed the oil, changed the spark plugs, etc. (de-winterization) with this kit, started and rode the jetski. It was struggling, wouldn't go past 15-20mph, with occasional misfire and gas smell.. I went home, and read the Kawasaki manual very carefully. When it comes to spark plugs, they explain in great detail how there may be more expensive spark plugs out there with fancy names, but there is something about this machine's computer / temperature of burn and what not and they very specifically state to get the regular spark plugs or risk of having issues. I bought new spark plugs per the book, changed them, and my machine is purring like new and flying over the water at super speed again. Here are the correct spark plugs for my machine (and likely for many other Kawasaki jetskis): NGK (2305) CR9EKB. This package again includes different plugs, so don't buy it until the seller starts including the correct ones.
