I've always used NGK plugs. When gapped correctly for my machine combined with proper carburetor tuning I've not once ever had an issue.

NGK is the best spark plug available. this particular plug is the highest performance model and is more reliable than the standard plugs.

I don't have much experience comparing the ins and outs of spark plugs, but I have yet to have any issues with this one. I recently had to rejet my carburetor as it was running quite rich, but I never had a fouled plug.

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.
