- Non-removable nut terminal and 14 mm hex size
- Champion Iridium 9019 cross-references NGK 94124
Product Details
The Champion Iridium line is built around precise spark delivery and stable ignition performance. Part number 9019 uses an iridium center electrode paired with a platinum ground electrode to support consistent firing characteristics in applications that call for a 0.044-inch gap. With its OE-style dimensions and resistor design, this spark plug is a practical replacement for vehicles that specify Champion Iridium or equivalent OE-type plugs.

What It Helps Address
- Rough idle caused by worn spark plug electrodes
- Hard starting from weakened ignition output
- Misfire conditions tied to excessive plug wear
- Reduced throttle response from inconsistent spark delivery
- Maintenance replacement for OE-style iridium plug applications
Installation Notes and Tips
Verify the required gap and thread specifications before installation, especially on Mazda CX-5, Mazda 3, and Mazda MX-5 Miata applications that call for a 0.042-inch or 0.044-inch gap depending on engine configuration. Confirm the seat type, thread diameter, and terminal style match the vehicle specification. Use proper spark plug service procedures and torque to the vehicle manufacturer’s specification.
