MAXIMUM PERFORMANCE: Every Double Platinum spark plug is necked-down center electrode fires quicker and cleaner, with less voltage for easier starts and quicker acceleration. Full copper core electrode provides better performance in all conditions.
IMPROVED DURABILITY: Our spark plugs are platinum-to-platinum firing for superior durability and super conductive Yttrium enhanced ground electrode provides superior heat transfer.
CONSTRUCTION: These spark plugs are platinum enhanced high nickel alloy side electrode maintains precision gap and assures virtually no gap erosion for longer plug life.
high nickel alloy side electrode maintains precise gap.
AUTOLITE ADVANTAGE: Autolite has been producing spark plugs since 1936 making it one of the most trusted and reliable brands for your OE replacement spark plugs needs.

Q179A is a gas pilot assembly (with a flame electrode rod) and ignition electrode, making it suitable for applications requiring an interrupted or intermittent electrically ignited gas pilot burner.
Primary aerated type burner is equipped with stainless steel fins that provide the proper flame rod area to ground area ratio for maximum flame signal and flame stabilization.
Stainless steel electrode(s) are mounted in ceramic insulators, which permit electrode adjustment.
Rajah connectors facilitate disconnecting (A1126 has terminal screws).

Revolutionary surface air gap firing technology featuring four yttrium-enhanced ground electrodes delivers the longest, most powerful spark for ultimate engine performance.
