• Platinum durability: a platinum center electrode resists wear to help keep spark performance stable over time.
• Sharp spark focus: a fine-wire center electrode paired with a V-trimmed ground electrode promotes accurate spark targeting and reliable ignition.
• Reduced fouling: a premium alloy quickly reaches and sustains the correct operating temperature.
• Corrosion resistance: a coated shell provides corrosion resistance in harsh environments.

It is a resistor-type plug (helps suppress ignition RFI), uses a flat seat with an included crush washer, and ships pre-gapped to simplify installation. Built to meet OE fit, form and function. Country of origin: Mexico. The quantity needed varies by engine — order one plug per cylinder and confirm the count for your vehicle in the Buyer's Guide.
