Hp Copper Spark Plug Ford 2008-2014 3-Valve 4.6L & 5.4L Eng Stock Heat Range 8 Pack Of Pn 354 ACCEL

ACCEL HP 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 HP 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 HP Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.
