Revolution HT Spark Plugs are a unique, patented design that results in more durability and greater power from a more comprehensive seal, improved heat transfer and more focused ignition power.
Features & Benefits:
Insulator - High alumina ceramic body
Spark Plug Assembly - Jam nut is "hot-pressed" onto the insulator/ground shield
Motor Seat - Contact area for sealing to engine cylinder head
Platinum alloy enhancement in "fine-wire" form on center electrode
Terminal Stud - Uses SAE1008 steel with nickel-plated finish
Jam Nut - 9/16" hex with 16 x 1.5-mm thread, nickel-plated steel
Resistor Seal - Conducting glass-seal terminations and carbon-based resistor
Copper-Core Center Electrode - Made with nickel-alloy sheath over a copper core (2.16-mm diameter)
This spark plug is pre-gapped, but may require minor adjustments with a Spark Plug Gap Tool / Feeler Gauge to match your engine's specifications. For proper engine performance, gaps should be within ±0.004" of OE-Recommended value.
