• Rough idle from inconsistent ignition performance
• Misfire conditions related to plug wear or gap drift
• Reduced throttle response from weak spark delivery
• Service intervals approaching the OE replacement schedule

Installation Notes

Verify the engine calls for a 0.044 in. gap, 12 mm thread diameter, flat seat, and the listed reach before installation. Use the vehicle service information for torque and removal procedures, and confirm the correct application by year, make, and model. For Nissan Altima, Nissan Rogue, and Chevrolet City Express service, match the OE-style high ignitability specification before replacing the plug.
