NGK has long supplied spark plugs for domestic and import vehicles in North America, and this part reflects that OE-focused approach. The ZFR5E-11 / 4435 spark plug is built to match the specified thread diameter, reach, seat type, and heat range for the listed applications, helping maintain proper combustion and ignition system operation.

This part cross-references Bosch 4029 and FR7HE02 for the same application.

Common Issues This Part Can Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Misfire conditions related to incorrect plug gap or electrode wear
• Reduced throttle response from aging ignition components
• Service interval maintenance on Nissan ignition systems

Installation Notes and Tips

• Verify the vehicle calls for a .044 in. spark plug gap before installation.
• Check the plug gap during service, even when pre-gapped from the factory.
• Confirm the 14 mm thread diameter, .75 in. reach, and flat seat match the cylinder head specification.
• Use the correct 5/8 in. spark plug socket for removal and installation.
• Apply proper torque per the vehicle service manual to avoid thread or sealing damage.
