How do I confirm fitment for my vehicle, and what installation tips should I follow?

Confirm fitment using a vehicle parts catalog, manufacturer specifications, or an online "confirm fit" tool before purchasing. When installing, work on a cold engine, torque to the manufacturer's specification and gap-check if required.

• Use confirmed-fit lookup by VIN or vehicle model to ensure compatibility.
• Install one plug at a time to preserve correct firing order and avoid cross-threading.
• Apply recommended torque and check the plug gap if your vehicle demands a specific tolerance.
