Detailed Description
Champion Iridium 9404 uses an iridium center electrode paired with a platinum ground electrode to deliver a concentrated spark kernel at the plug gap. The J-gap layout and fine-wire center electrode help maintain consistent ignition characteristics, while the resistor design supports stable operation in modern ignition systems. With a 14 mm thread diameter, 0.689 in reach, and tapered seat, this plug matches OE-style specifications for many applications that call for RS14WYPB5.
This part cross-references DENSO Auto Parts 4504 and Autolite XP105 for the same application. It is a practical replacement choice for drivers searching for Champion 9404 spark plug fitment on Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Express 1500, and related vehicles.
What It Helps Address
- Hard starting caused by worn spark plugs
- Rough idle from weak or inconsistent spark delivery
- Misfire conditions tied to electrode wear
- Reduced throttle response from degraded ignition performance
- Maintenance replacement for OE-style ignition service
Installation Notes and Tips
- Verify the vehicle calls for plug type RS14WYPB5 before installation.
- Confirm the specified gap for the application; listed fitments vary by vehicle and year.
