NGK (4218) CR8EIX Iridium IX Spark Plug, Pack of 1

Works great on my klx300. Simple swap and it runs better.

Beautiful piece, original NGK

I own three motorcycles. When it is time to change out the plugs, I always pay the extra money and buy Iridium plugs. They cost anywhere from $7-$10 each, so they are not cheap, but I want my bike running perfect and purring like a cat while riding a short distance through the mountains or taking off across country. No hassles, no problems. My bike starts first time, everytime, runs smooth, great mileage and no problems while away from home. So, are these worth the price difference? Because I ride about 20,000 miles yearly, I would rather pay the difference for idea plugs and enjoy worry free riding instead of possibly having a break-down somewhere far from home. They give me piece of mind. Money well spent. Buying NGK is a personal preference. I have used NGK in my street-bikes, ATV's and in my younger years I used NGK in my dirt bikes. I'm content with their performance and longevity. UPDATE: I just purchased my second set of these NGK CR8EIX plugs for my 2008 Yamaha FJR1300. They work great in my street bike, I also put them in both ATV's, my 2012 Yamaha WR450F and my Suzuki 650 Burgman. I prefer these plugs because they don't foul under any circumstances. I am replacing these after 24,000 miles in my FJR simply because I am preparing my bike for a long road trip, so regardless of how long they may last, I want new plugs for this trip. I consider it just one additional step in my preparation for a long road trip and don't want to have any interruptions of any kind. Cost, yes they are a few extra dollars, but so what. If you can't afford to run the best, perhaps you should consider changing your lifestyle! Do you pay a little extra for a better air filter, better tires, better riding gear, then don't sweat the small stuff, take care of your machine so it can take care of you!

Excelente

Works well, fits my 2008 Yfz450. Top has to be screwed off to reveal smaller contact. Not too sure about the longevity

Excellent product

The iridium spark plug is an upgrade to the original spark plug. If your scooter calls for CR8EB, then you can get this for a small performance and durability upgrade when it comes time to replace your spark plugs.

Bought this plug to try in my Aprilia Scooter. I wanted to see if I had a performance change using the Iridium plug. I really can't notice any big improvements. Too early to tell if mileage gets better. The plug comes with a threaded end and I needed a terminal cap to use it with my scooter - that was hard to find - parts store guy stole one off another plug and gave it to me - none of the parts houses here in Boise carry the terminal screw on cap - what a pain - I suggest (the manufacturer) putting one on the plug and letting us (the consumer) take it off if we don't need it, instead of making us search for one if we do. :)>>
