P526S ACCEL Double Platinum Shorty Spark Plug

ACCEL's redesigned C-Cut high-performance spark plug delivers significantly more power at high rpm thanks to a ground electrode that unshrouds the center electrode. This creates a considerably hotter spark and lets the flame expand more rapidly in the chamber, creating a huge increase in power, reducing misfire, minimizing flame dissipation, and giving you instant throttle response and noticeably better fuel economy. This specially designed copper-core plug provides increased thermal conductivity, comes with machine-rolled 14mm threads to protect your valuable cylinder heads, and is backed by a limited one-year warranty.
