Before You Buy

Installation Notes

• Confirm NGK 7938 / BKR5E is correct for your specific vehicle and engine before installation.
• Check the spark plug gap before installation. Although the spark plugs are pre-gapped for general use, the gap may need to be adjusted to meet your specific vehicle manufacturer's specifications.
• Install spark plugs only when the engine is cool.
• Avoid dropping or damaging the spark plug electrode and insulator during installation.
• Thread each spark plug into the cylinder head carefully to help prevent cross-threading.
• Tighten the spark plugs according to the vehicle or engine manufacturer's specified installation procedure and torque.

Important: These spark plugs are pre-gapped for general use; however, the required spark plug gap can vary by application. Always check and adjust the gap to your vehicle manufacturer's specification before installation.
