  • Misfire conditions tied to plug wear or incorrect gap
  • Reduced throttle response from degraded ignition performance
  • Maintenance replacement for vehicles calling for RE14WLPB5

Installation Notes and Tips

Verify the vehicle’s required plug type, seat style, thread diameter, and gap before installation. Champion 9440 is listed with a 0.053 in. pre-gap, while several fitments note a 0.050 in. gap requirement, so confirm the exact specification for the application before use. Use proper spark plug service procedures and torque to the vehicle manufacturer’s specification.

Quality Assurance

Champion Iridium spark plugs use iridium and platinum electrode materials for durable ignition service and consistent spark focus. Confirm fitment against the vehicle’s OE plug specification and engine requirements before installation.
