ACCEL C-Cut Performance Spark Plugs

ACCEL C-Cut Performance spark plugs ignite a better path to high performance for both street and strip applications. Their ground strap aligns with the centerline of the electrode to create a much-improved electrical pathway. This design reduces quenching, shrouding, and obstruction, allowing a hotter, larger flame, better firing energy, and a complete burn. Unshroud the spark to ignite your vehicle's performance; order the ACCEL C-Cut Performance spark plugs designed to fit your engine. More product features include: * Greater fuel efficiency, reduced emissions, increased performance, and better throttle response * Helps eliminate misfiring, rough idle, and overall poor performance * Copper core outperforms iridium and platinum * Machine-rolled threads protect your valuable cylinder heads * Sizes and sets available for thousands of applications
