Champion Iridium Spark Plug 9412
Champion Iridium 9412 is a secondary ignition spark plug built for precise spark delivery and stable combustion. Its fine-wire iridium center electrode and platinum ground electrode focus the spark for consistent performance in a wide range of late-model import and domestic applications.
Key Features
- Fine-wire iridium center electrode for sharp spark focus
- Platinum ground electrode with J-gap design
- Pre-gapped at 0.041 in / 1.05 mm
- Resistor-type construction for ignition system noise control
- Flat seat design with non-removable nut terminal
- Heat range 9 for specified OE-style applications
- Cross-reference: this part cross-references Autolite XP5683 and XP5684 for the same application
Product Details
Champion Iridium 9412 uses an iridium center electrode and a platinum ground electrode pad to create a focused spark kernel at the plug tip. That electrode combination supports clean ignition events and consistent firing characteristics in engines that specify the REA9WYPB4 plug type. The J-gap layout, flat seat, and resistor design align with OE-style service requirements across many Honda Civic, Nissan Altima, and Subaru Impreza applications, along with additional coverage for Acura, INFINITI, Toyota, Jaguar, and other listed vehicles. This part number is 9412.
What This Spark Plug Helps Address
- Rough idle caused by worn or inconsistent spark plugs
- Hard starting from weakened ignition output
- Misfire conditions tied to plug wear or incorrect gap
- Reduced throttle response from unstable combustion
- Service replacement for OE-style REA9WYPB4 applications
Installation Notes and Fitment
Verify the required gap and plug type before installation. This plug is pre-gapped at 0.041 in, while several listed applications call for 0.043 in, 0.044 in, 0.040 in, 0.036 in, 0.035 in, or 0.032 in depending on the vehicle.
