* Purchasing in units of 10 (one box) does not guarantee delivery in a single box.

Features a D-Shape outer electrode and ruthenium-based center electrode designed specifically for motorcycle engines. This combination improves acceleration, durability, anti-fouling performance, fuel efficiency, and starting reliability.
The D-shaped cross-section of the outer electrode minimizes obstruction to the air-fuel mixture flow, guiding it efficiently into the spark gap and promoting ideal, near-spherical flame propagation for superior combustion efficiency.
The plug features a copper-cored center electrode that dissipates heat rapidly, providing a wide heat range that resists both overheating and fouling. The high-grade alumina ceramic insulator ensures excellent electrical insulation at high temperatures, thermal shock resistance, and mechanical strength. The structure is reinforced with special powder bonding for airtight integrity and durability. Integrated corrugation on the insulator prevents flashover by increasing the surface distance between the terminal and the metal shell.

Points of Attention

* If there may be an instruction manual included, it will be written in Japanese.

It's a bit expensive, but I expect it to perform.

Very good spark plug

My motorcycle is YAMAHA NMAX155. It's time to replace the spark plug. I don't want to replace the original model. I bought this NGK MotoDX spark plug on webike. This model is a high-end model of NGK, which can effectively reduce the ignition delay and improve the service life. After replacement, the actual experience is accelerated rapidly, which is much better than the original performance

I bought it for a replacement cycle after replacing it last time and riding it for about 5000km.

I'm not an expert, but after replacing it with the DX last time, the throttle response improved and I felt that the ride was better than using the genuine one, so I bought an additional replacement after 5000km.Unless there is a big problem, I think I will probably continue to purchase and use the MOTO DX.

Looking forward to a long life

2019 DL1000 V-STROM 650, first replacement at 15,000 km. The plug that was removed was still usable with proper Gap, minimal Edge wear, and good burn color.The difference from the MotoDX replacement is a little smoother? I think the only difference is that the MotoDX is a little smoother and the Merit is long life. I didn't expect any improvement in running performance, and what is the basis for the short life of the StandardPlug that PlugManufacturer says? I doubt it.

Slightly higher fuel economy.

Motorcycle-only Plug is something I would like to include.
I put it in with BirdCity's Refresh.

The fuel consumption seems to have improved, although it is not more than 2 km per liter.
I honestly didn't know about Torque, etc., but I was excited because I didn't think I would be replacing the Scooter plugs very often.
