NGK(7544) CR7HIX Iridium IX Spark Plug, Pack of 1

Using this in a 49cc gas bike that I use daily. Can definitely tell the difference from the original cheap plug it came with and this. Fits great, gapsping was on point, and performs excellent. Built to last and worth the money.

I recently acquired a used TTR-125 for my lady and, since it was used, I decided to rebuild the carb and do a tune-up as soon as I got it. Since iridium plugs are supposed to be less prone to fouling, I decided to give this a try in her bike. I know some people make claims of these providing more power but I purchased this entirely for the purpose of having a plug that is more resistant to fouling. Since it's a small displacement engine anyhow, I really don't think this plug makes any difference in power but I can say that I've had zero issues related to spark with this plug. The bike fires quickly (usually within 2 kicks) and once it's running we have had zero issues with the bike performing perfectly, even with it being an older 2004 model. Definitely worth the little bit of extra cost for the added piece of mind.

I took a chance on this NGK plug. My Kymco Agility 50 is 3 years old and figured I'd replace it. I pulled the old NKG plug out and replaced it with a similar Autolite that I got at a local box store. The old plug had worked much better and put it back in.Then I saw this Iridium and bought it. Put it in my scooter this morning and immediately saw a big difference just when I pushed the starter button. Boom! The engine burst into life immediately.My quick test drive turned into a 100+ mile tour. The engine was quicker and more responsive than it had ever been before. It was as if I'd given the scooter a major tuneup. I'm not kidding when it seemed as if my little 50cc had grown bigger, that somehow the engine had increased in size to a 60cc.The extra $$$ spent on this plug is totally worth it. At least so far. I really hope that the new performance I've seen keeps on going as I putter my new scooter down the road.

Seems to be a great spark plug. Using on a 1992 Yamaha breeze (YFA-1). It had been sitting for about three years after it got to be too small for my boy. We cleaned the carb, flushed the fuel lines, changed the oil, put in the new plug and she fired right up. Now the four wheeler passes down to my ten year old girl.

I upgraded to this plug for my two Tao Tao ATM 50cc scooters. Not a huge jump in performance (even though I swapped out the stock spark plug caps to a higher performance model at the same time), but it was easy to install after watching a YouTube video, and the online mechanic types think it will do well for the long haul. The scooters both seem to idle better with this new plug, but on the road they still accelerate at about the same rate.

If you can afford to get this, get it. I read warnings about plug gapping and all that. I did not gap just to see how it would run. Well, it started right away and it idled a lot smoother than it had before. Did not have to blip throttle to keep it from dying. It's like my scooter is already warmed up when it first started. The only thing I had to do was decrease idle speed a tiny bit and that's it. It's a real NGK Iridium and it did make difference for me.
