They are the original spark plugs that come in most Honda jet skis, mine was an R-12X. They worked fine and eliminated misfiring issues I was having.

Crazy expensive spark plugs, but they're literally the only ones for the amazing Honda AquaTrax PWCs. I use these in my 2006 R-12X Turbo and it's AMAZING the difference new plugs make it run. If your engine is running rough... not hitting max RPM... or having problems maintaining idle, do yourself a favor and get a new set of 4 of these puppies. Actually... get 8. That way you always have a spare pair. Save the trip to the dealer/repair shop... totally worth trying to swap these out first.

I bought these for my 2004 F-12X, exact oem replacement. I install new plugs every year at the start of the season when I dewinterize it and service it. These are the same ones sold at the dealership that cost $17 each, so this saved me alot of greenbacks, plus I didn't have to burn gas getting them, they shipped free. Totally happy, now time to enjoy the water.

I think these spark plugs are over priced, but they do work and the jet ski rides. I am still not getting the same power I did last year but that might be due to another problem

NGK IMR9d-9H is for my Honda Aquatrax Turbo Jet Ski. Upon liberal application of fogging oil during a winterization process, my old plugs fouled badly and needed replacement. These plugs foul easily. But the new ones are amazing....burns cleanly and produces tremendous efficiency. I'm actually getting about 3 extra MPH after installing new plugs from what I was getting last summer. Very pleased with these plugs and well worth the investment.Amazon 2 day shipping is another story. I purchased with 2 day shipping so I could install them over the weekend......Amazon delayed the shipment, out of stock I presume, so I wasn't able to install them over the weekend.
