Product Details

The Autolite Copper Resistor Spark Plug line is positioned as an OE-style replacement for everyday drivability and service intervals. Part number 5325 uses a copper core center electrode, nickel ground electrode, and a resistor-type design to support stable ignition performance across a broad range of engines. With its standard regular center electrode design and tapered ground electrode tip, this plug is specified for many fitments that call for a 0.044 in. gap, including several Toyota, Lexus, Audi, and Volkswagen applications.

This part cross-references Anchor 6076 and Continental 5018 for the same application.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle and inconsistent combustion
• Reduced throttle response during acceleration
• Misfire conditions related to ignition wear
• Service replacement needs on OE-style ignition systems

Installation Notes

• Verify the vehicle-specific gap before installation; listed applications include 0.044 in., 0.040 in., 0.032 in., 0.031 in., 0.030 in., 0.028 in., and 0.050 in. requirements depending on engine and model year.
• Confirm the exact engine application for vehicles with special notes such as dual-plug cylinder designs.
• Use the fitment notes for model-specific guidance on Audi A6 Quattro, Lexus RX350, Toyota Camry, and Volkswagen GTI applications.
• Check thread diameter, reach, seat type, and terminal style against the original plug before installation.
