Product Details

Champion Iridium 9008 is engineered for consistent ignition performance where a precise spark and stable electrode design matter. The iridium center tip helps concentrate the spark, while the platinum ground electrode supports long-term durability in everyday driving and maintenance intervals. This plug is listed with a heat range of 10 and a resistor design, and it cross-references NGK 94167 for the same application.

For fitment-based searches, this spark plug is listed for applications such as Fits 2011-2016 Honda CR-Z, N/A; Fits 2011-2014 Mazda 2, N/A; Fits 2004-2005 Mazda 3, N/A; and Fits 1999-2000 Honda Civic, N/A.

What It Helps Address

• Rough idle caused by worn spark plug electrodes
• Hard starting from weak or inconsistent spark output
• Misfire complaints tied to aged secondary ignition components
• Reduced throttle response from degraded plug performance
• Maintenance service needs on OE-style ignition systems

Installation Notes and Tips

Verify plug type RC10WYPB5, thread diameter, reach, seat style, and gap before installation. Confirm the vehicle’s required gap specification against the application notes, since listed fitments include different OE gap references. Use proper spark plug service procedures and torque to the vehicle manufacturer’s specification. Check coil boots, wires, and ignition components during replacement to avoid repeat misfire concerns.

Quality Assurance

Champion Iridium plugs are built for secondary ignition service with iridium and platinum electrode materials selected for controlled spark delivery and durable operation. Confirm the part number 9008 against the vehicle application before ordering.
