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.

Frequently Asked Questions
Q: What are the benefits of using the ACCEL 0576S-4 HP Copper Spark Plug?A: The ACCEL 0576S-4 HP Copper Spark Plug features a shorter design that enhances clearance for tubular exhaust headers, preventing dimpling and facilitating easier access for installation and removal. Its copper core provides superior conductivity and heat dissipation, resulting in a stronger spark and reduced chances of misfires, especially in high-performance applications.
Q: Is the ACCEL Shorty Spark Plug compatible with all vehicles?A: The ACCEL Shorty Spark Plugs are designed for specific applications, particularly those with limited space around the spark plugs, such as vehicles with tubular exhaust headers. It is essential to check the compatibility with your vehicle's make and model to ensure proper fit and performance.
Q: How do I install the ACCEL 0576S-4 Spark Plug?A: To install the ACCEL 0576S-4 Spark Plug, first ensure the engine is cool. Remove the old spark plug using a suitable socket. Apply anti-seize compound to the threads of the new spark plug, then carefully screw it into place by hand. Finally, tighten it to the manufacturer's specifications using a torque wrench to ensure proper engagement.
Q: Can I adjust the gap on the ACCEL Shorty Spark Plug?A: Yes, the ACCEL Shorty Spark Plugs are gapable. You can adjust the spark plug gap to expose a larger flame kernel for better ignition or close it for high boost applications. It’s important to use a proper gap tool to achieve the desired setting without damaging the electrode.
Q: How do I know when to replace my ACCEL Spark Plugs?A: Signs that it may be time to replace your ACCEL Spark Plugs include difficulty starting the engine, poor fuel economy, rough idling, or a noticeable decrease in performance. Regular inspection every 30,000 miles is recommended, but consult your vehicle’s manual for specific replacement intervals.
