• Platinum ground electrode core for durability
• J-gap ground electrode tip design
• Pre-gapped at 0.041 in. / 1.05 mm
• Resistor type spark plug
• Flat seat design with 14 mm thread diameter
• 1.043 in. reach and 0.625 in. hex size
• Champion Iridium line for OE-style ignition service

Product Details

Champion 9033 uses an iridium center electrode and platinum ground electrode to support a focused spark event and stable ignition performance. Its OE-type configuration and REC8WYPB4 plug type make it a direct-match service part for a wide range of import applications, including 2006-2011 Honda Civic, 2005-2015 Toyota Tacoma, and 2005-2011 Toyota Tundra. This part cross-references NGK 5468 for the same application.

The Champion Iridium product line is built around fine-wire electrode construction for modern engines that require accurate spark placement and dependable secondary ignition service. For drivers maintaining a Honda Insight, Toyota FJ Cruiser, or Saab 9-5, part number 9033 provides the specified plug format for those OE-style applications.

What It Helps Address

• Rough idle caused by worn spark plug electrodes
• Hard starting from weak or inconsistent spark output
• Misfire conditions related to ignition wear
• Reduced throttle response from degraded secondary ignition performance
• Maintenance replacement for OE-style spark plug service intervals

Installation Notes

• Verify the plug type, thread diameter, reach, seat type, and heat range before installation.
• Confirm the specified gap for the vehicle application; listed pre-gap is 0.041 in. / 1.05 mm, while some fitments note a 0.044 in. or 0.040 in. requirement.
• Use the correct torque procedure for the cylinder head material and plug seat style.
• Check vehicle-specific service information for access, coil removal, and final gap verification.

Quality Assurance

Champion 9033 is part of the Champion Iridium spark plug line and is built with iridium and platinum electrode materials for OE-style ignition service. Confirm fitment against the vehicle’s engine code and plug specification before installation.
