High-Performance Design. While not as long-lasting as iridium or platinum spark plugs, copper spark plugs offer several performance benefits overstock. Copper plugs are gapable, unlike platinum and iridium counterparts, allowing you to adjust the spark intensity for variable performance. Copper plugs also run far cooler, allowing you to push your vehicle harder without the risk of burning/melting an electrode. Additionally, copper plugs tend to operate more efficiently, offering superior spark, efficient combustion, and more power!

Pack of 8. This product includes 8 high-performance spark plugs, allowing you to replace all plugs on both banks for consistent performance. 

Machine-Rolled Threads. Your ride is notorious for stripping spark plug threads, with improperly torqued plugs often shooting from the cylinder heads, taking the aluminum threads with them. Luckily, Accel HP spark plugs utilize machine-rolled threads, offering better engagement and more accurate torque values to reduce the risk of thread damage. 

Warranty. A limited 1-year warranty covers this product against manufacturing defects. The warranty is reduced to 90 days if used in competition. 

Application. These Accel HP Spark Plugs fit all Late 2008-2010 Ford Mustang GT and GT500 models.
