I threw this NGK Iridium plug in for my rebuild and it fired right up on the first kick. The fine-wire iridium tip gives you a crisp, clean spark every time, and throttle response feels sharp all the way through the rev range. It resists fouling way better than a standard copper plug, so you don't have to worry about it quitting on you out on the trail or track. Easily the best insurance for quick starts and consistent performance.

Bought a 2nd 400ex for my son. His had an electrical nightmare. I plugged my oem into his machine and it instantly fried my OEM CDI box. Purchased 2 of these through RMATV, and my 400ex instantly fired up. Continued to try to get my sons 400ex running (now it has spark) but it needs more than a different box. Went to hop on my 400ex and the new CDI box malfunctioned. Swapped it out with the other unit I purchased from RMATV and it fired right up.

Grabbed this G-Rated plug for a bit of a performance boost, and it doesn't disappoint. Just like the standard NGK plugs, the quality is top-notch, it threads in perfectly, and it fires clean every single time. It gives a nice, crisp response and holds up great under hard riding. If you want a little extra reliability and a clean burn, these are definitely the way to go.

I have been running NGK plugs in all my motorcycles and ATVs for the past 20 years. I absolutely love them because they are great quality and just work. They plug right in, spark clean, and last a long time under hard riding. When a plug is this reliable for two decades, there's no reason to buy anything else.

The Trail Tech Vapor is easy to install and use. The Vapor provides all the information needed to turn a dirt bike into a duel Make sure you check the battery, mine shipped with a dead battery. Easy enough to replace.
