Autolite 766 Copper Resistor Automotive Replacement Spark Plugs (4 Pack)
Customize
Autolite 766 Copper Resistor spark plugs (4 pack) deliver reliable ignition performance and value. These copper-core resistor plugs provide quick starts, better fuel economy and smooth acceleration. They feature a copper-glass seal bonding the insulator and terminal post center electrode to ensure full required voltage at the spark gap and a 100% leak-proof gas-tight seal. Construction includes a cold-formed steel shell, precision rolled threads, and a one-piece terminal post for strength. The multi-rib insulator reduces flash-over to prevent misfires, and the resistor reduces radio frequency interference (RFI) and electrode erosion. The full copper core electrode provides higher thermal conductivity for consistent performance in varied conditions. Packaged as a 4-count replacement set; nominal product dimensions (per internal item data) are 6.31 x 3.27 x 0.81 inches and item weight (internal) is 0.5000 pounds.
