Top 10 Best Autolite 3924 Spark Plug

Copper-glass seal bonds insulator, terminal post, and center electrode together to provide a tight seal that is 100 percent leak-proof. Cold-formed steel shell and precision rolled threads, with one-piece terminal post to add strength. Multi-rib insulator reduces danger of flash-over. Resistor reduces radio frequency interference RFI and electrode erosion. Full copper core electrode provides better performance in all conditions.

Sold in packs of 4.

Full platinum tip ensures virtually no gap erosion for long plug life. Yttrium enhanced, high nickel alloy side electrode maintains precise gap to increase plug life. Necked-down center electrode fires quicker and cleaner, with less voltage for easier starts, quicker acceleration, and improved fuel economy. Platinum alloy pad on ground electrode provides extended durability and service life and platinum-to-platinum firing. Nickel-plated steel shell for long-life corrosion resistance.
