14mm Thread Size, 25.4mm (1") Reach, 5/8" (16mm) Hex Size, Tapered Seat, Resistor, Copper Core, Platinum Tipped Center Electrode and Platinum Tipped Ground Electrode, Power Tip, Full Thread Size, Heat Range 4
Autolite Double Platinum delivers peak engine performance with virtually no gap erosion. It does this with platinum to platinum firing tips on both the ground and center electrodes. Originally designed for Distributorless ignition systems(DIS), any car can benefit from the long life high performance features as well as the top fuel efficiency over the extended life of this plug. Resistor plugs minimize electronic interference and can aid in reducing electrode erosion. Copper core aids in cooling and improves resistance to fouling. Power tip or extended electrode plugs project the firing tip into the combustion chamber which not only aids in cooling but also cleaning so that fouling is reduced at low RPM. Half threaded shell was designed for automated installation at the time of engine assembly. The half thread plugs are duplicates of the full thread plugs in every other aspect, they both protrude the same amount into the combustion chamber. |
