Product Details
The Champion Iridium line is built around a fine-wire iridium center electrode paired with a platinum ground electrode to concentrate the spark and support stable ignition performance. This plug uses a J-gap configuration, a non-removable nut terminal, and a tapered seat, making it a direct-match style service part for many late-model and older performance or truck applications. Champion 9808 is listed for vehicles such as the Ford E-350 Super Duty, Ford Mustang, Chevrolet Corvette, Cadillac CTS, and Aston Martin DB9, with application-specific gap requirements noted in the fitment data.
This part cross-references Monroe Shocks & Struts (e.g., 5809) for the same application.
Common Uses
- Restoring weak spark or misfire conditions tied to worn plugs
- Replacing plugs with excessive electrode wear or widened gap
- Addressing rough idle, hesitation, or hard starting caused by ignition wear
- Maintaining ignition performance in Ford E-150, Ford F-150, and Ford Mustang applications
- Servicing Chevrolet Corvette, Cadillac CTS, and Aston Martin V12 Vantage applications
Installation Notes
Verify the required gap before installation, since listed applications vary by vehicle and engine calibration. Confirm tapered-seat compatibility, 14 mm thread size, 0.689 in reach, and the correct plug type RS8WYPB5 before service. Use the vehicle-specific gap shown in the fitment notes for Ford, Chevrolet, Cadillac, and Aston Martin applications, and follow the manufacturer torque specification during installation.
Quality Assurance
Champion Iridium 9808 is built with iridium and platinum electrode materials for durable ignition service and consistent spark delivery. The plug specification data, including heat range 8 and resistor design, supports accurate parts matching for maintenance and repair work.
