NGK V power 7 spark plug

 
Recommended for 300cc models only  2023-2025 applications. This is a special V power plug from NGK.  It's listed as a 7 heat range but NGK says it's more like a 7.5. It has a slightly extended electrode, which casues the combustion process to start and complete a little sooner. Throttle response is improved over the stock plug, and performs even better than the iridium plug.
