Hp Copper Spark Plug 14MM Thread .708 In Reach Tapered Seat 4 Pack ACCEL

The ACCEL 0526-4 is a pack of four HP Copper Spark Plugs. These spark plugs feature a copper core, which is a better conductor than platinum and iridium, delivering a stronger spark, especially in high-performance applications. The copper construction also aids in heat dissipation, reducing the chance of misfires.

Designed with machine-rolled 14mm threads, these spark plugs offer precise thread engagement and reliable torque retention to protect your cylinder heads. They are gapable, allowing for adjustments to expose a larger flame kernel or to close the gap for high boost applications. The plugs have a .060 inch gap, a .708 inch reach, and a tapered seat.
