Amazing
amazing spark plug. works really great with my 2002 honda xr200. It was somewhat hard for a beginner in motorcycle mechanic because it has a cap on it that you have to take off, for my bike in particular. This thing really makes my bike rip like crazy, the power and speed, and really the bang for your buck if your looking for a tuned spark plug

It works, but no difference to note.
Used in a Gen 2 KLR 650, my plug came with an almost closed gap. Not a big deal, you should be checking your gap before install anyway (don’t just trust that it’s been gapped appropriately for you) but after install I haven’t noticed a single difference. Not in how my bike starts, runs, or anything. Manufacturer recommends .8 to .9 and I set mine to .88 . I’ll probably just run the regular NGK plugs after this.

High Quality, Genuine Plugs
I run these plugs in my two motorcycles, and they have performed exceptionally well. However, there is some concern about counterfeit copies being sold which are very difficult to distinguish from the genuine models. I purchased my last set of these in June 2023 and they were sold and shipped by Amazon, which I think is an important factor. I contacted NGK/Niterra product support directly to confirm that these plugs are genuine, and they had me send them three pictures so they could evaluate. Within minutes they responded that the plugs are genuine, which is excellent support. You can purchase these with confidence, and if you have any question, you can always contact the manufacturer directly.

Reçu en bonne état. Correspond à la référence modèle. Depuis le montage, roulé 50 km. Sensiblement meilleur à l'allumage qu'une bougie classique. A voir sur la durée.

I've used these plugs in every single motorcycle I've restored using the same heat rating/plug ID but going to an iridium tip. These plugs start better and have way better throttle response. They provide the best power compared to many other plugs I've tested in real-world conditions. The only plug that came close was the E3. Standard plugs are 1/2 the price but if you're riding a performance bike, these plugs definitely make a difference you can feel.
