Autolite aluminum core spark plugs Feature a cold-formed metal casing with precision-rolled threads, also a complete copper core electrode for superior efficiency, and also a one-piece terminal pole in order to include energy. The ignition sticks use a copper-glass cachet that bonds the insulator and final post heart electrode jointly. This guarantees complete voltage in the spark gap and also a 100-percent Nominal, gastight seal. autolite 3924 comes with a comprehensive program guide to insure just about everything using an internal combustion engine. Keep your motor running easily and reliably with Autolite replacement copper core spark plugs.

Benefits and features

Secured to deliver fast starts, Very good fuel economy, and easy acceleration. The copper core increases the speed of heat conduction from the spark plug hint and improves resistance to all sorts of fouling. 3924 Autolite has Copper-glass seal bonds insulator, terminal post center electrode together; assures full required voltage in spark gap; gas tight seal (100% leak proof). Multi-rib insulator reduces the chance of”flash-over”. Onepiece terminal post adds strength. Resistor reduces radio frequency interference (RFI) and electrode erosion. Cold-formed metal casing accuracy wrapped threads. The full aluminum core electrode provides improved efficiency in several ailments.
