NGK CR8EIX Iridium IX Spark Plug for Enhanced Performance - 1 Pack Review

Bought for my Suzuki. Others had some coal on them and didn't make the engine run any better. I went the better route and spent more on Iridium than regular copper simply because it's a motorcycle and hard to come by. Works great and performs well up to 12,000rpm!

Works on my 2000 SV650. I like these over the brass ones because I know they'll give me a little more time. Copper is best for performance, but changing the spark plugs on my bike requires removing the radiator and draining the coolant, which isn't much fun on a clean bike like mine. Works great, just like the originals before it. Distance up to 0.028

I bought these for my FJR-1300 when I needed to change the spark plug. They already came for the right release, which I don't know if they're promoting. I bought them to last longer. Others have indicated that they get better performance and different concepts, but I haven't felt or noticed any difference myself. Time will tell if the price difference was worth it.

NGK is by far the best spark plug for your quad. I've tried other brands and none lasted more than a few rides before needing replacement. My quad only runs on 107 octane or better gas due to the high compression ratio, so I throw out spark plugs very quickly due to the extra heat generated by the combustion. NGK are the only spark plugs I've ever used that last over a month before needing replacement.

After making some modifications to my RE Himalayan I decided to go the Iridium route to ensure extra fuel burns out. I wouldn't recommend this on a standard engine, but by adding a fuel booster, higher flow filter and exhaust I wanted to make sure the spark matched the rest. I'd like to note that if you don't think this is suitable for the Himalayas, remember that the cap can be unscrewed to fit a smaller diameter connector that standard cables require.

I own three motorcycles. When it comes time to change the candles, I always pay extra and buy iridium candles. They're between $7-$10 each so aren't cheap, but I want my bike to perform perfectly and purr like a cat when I'm riding a short distance through the mountains or starting cross country. No hassle, no problem. My bike starts first time every time, runs smooth, has high mileage and no issues when I'm away from home. So are they worth the price difference? Since I drive about 20,000…
