What are the key specifications and installation notes?

These plugs use a nickel tip with a V-groove electrode and follow NGK's standard design. Always verify compatibility with your vehicle's make, model, engine code, and the manufacturer's recommended gap before installation. Use a torque wrench and anti-seize only if specified by the vehicle maker.

• Tip material: nickel with V-groove for consistent spark
• Sold in sets of four for multi-cylinder engines
• Confirm heat range and gap to match vehicle requirements
• Follow factory torque and installation procedures to avoid damage

When should these plugs be replaced or inspected?

Inspect spark plugs during regular maintenance intervals or if you notice rough idling, misfires, or poor fuel economy. Replacement frequency depends on driving conditions and engine type; standard NGK plugs typically last through multiple service intervals but should be checked visually for wear or deposits.

• Check during scheduled tune-ups or if symptoms appear
• Replace plugs showing heavy wear, fouling, or altered gap
• Use NGK part numbers to ensure correct replacements
