Accel Platinum Spark Plugs for Buell HD Big Twin Cam 86-10

ACCEL Motorcycle Platinum Spark Plug Shop Packs deliver significantly more power at high rpm thanks to a ground electrode that unshrouds the center electrode. Their durable platinum tip maintains the proper gap much longer than ordinary plugs and lets the flame expand more rapidly in the chamber, boosting power, reducing misfire, minimizing flame dissipation, and giving you instant throttle response and noticeably better fuel economy. This specially designed copper-core plug comes in a pack of 24, ignites standard and high-compression engines, and is backed by a 90-day limited warranty.
