• Champion Iridium line focused on performance-grade secondary ignition

Product Details

Champion Iridium 9110 is engineered as a performance spark plug for modern Nissan engines that call for a REA12WMB4-style plug. The iridium center electrode measures 0.078 in. and uses a fine-wire design to concentrate the spark, while the iridium-platinum ground electrode tip supports stable ignition under demanding operating conditions. With a 12 heat range, 1.043 in. reach, and flat seat construction, this plug is built to match the specified secondary ignition requirements for the listed applications. This part cross-references NGK 94702 for the same application. Champion 9110 is a practical choice for Nissan Altima, Frontier, Rogue, Sentra, Versa, Versa Note, and Rogue Select service work where the correct plug specification matters.

Installation Notes

Verify the plug specification against the engine’s required REA12WMB4-equivalent application before installation. Check the pre-gap setting, thread diameter, reach, seat type, and terminal style to confirm match-up with the vehicle’s ignition system. Use proper spark plug service procedures and torque to the manufacturer’s specification for the engine being serviced. For Nissan Altima, Frontier, Rogue, Sentra, Versa, Versa Note, and Rogue Select applications, confirm cylinder head condition and inspect ignition coils during plug replacement.
