The Denso IXU27 is the correct plug, but I can tell you they are not worth the extra expense. I used to run them and went back to the stock NGK plugs.
The Denso's would not last any longer than the stock plugs which are only $3.50 each

The Densos' Work well if you are a tad rich and have no way to adjust on your ski...Back when RRFPR and fuel controllers were not heard of in our PWC world I ran the NGKs and the ski would spit and sputter until the ski would warm up..I switched to the Densos and the ski never did that again...My setup is now completely different but i am still using the same plugs with no issues...

Ive only had one plug foul and it was an OEM one believe it or not..LOL..Plug choices are all ones preference,some say this one works while others say that one works,its whatever works the best in your ski..The OEM ones do work well with little issues and are a 1/3rd cheaper than the Densos..

My ski is rich at idle 11:1. The ski starts and idles better with the Densos. I put 100 hours on my first set of Densos.
