Accell 0437S-4 - Spark Plug, HP Copper, 0437S, Shorty

ACCEL's patented race proven spark plugs in a Shorty configuration. The overall length has been reduced 3/16 in to 3/8 in (depending on the specific spark plug) to gain critical air gap between the spark plug boot and the exhaust manifold or header tube. This helps eliminate burning the spark plug boot or dimpling the header tube. The shorter spark plug length also can make it easier to install an remove the spark plugs in certain applications where there is not a lot of room to fit a socket or move a wrench around. ACCEL Shorty Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire. ACCEL Shorty Spark Plugs are gapable allowing you to open the gap exposing a larger flame kernel or close it if needed for high boost applications. All ACCEL Shorty Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.

ACCEL C-Cut Copper Spark Plugs are designed to create a significantly hotter and more direct spark, allowing the flame to expand rapidly through the combustion chamber. The unique C-Cut electrode layout positions the spark directly above the midpoint of the electrode core, preventing it from being shrouded by the ground strap. This open design provides the flame with an unobstructed space to grow, creating a larger flame front and a far more complete burn of the air-fuel mixture.
The result is a more efficient and complete combustion cycle, which enhances throttle response, supports increased performance, improves fuel efficiency, and helps reduce emissions. ACCEL has long been recognized for its innovative grounding and electrode designs that improve ignitability and combustion quality, and the C-Cut Copper series continues this legacy with a refined architecture that delivers measurable ignition improvements right where it matters most: inside the cylinder.
