Product Details

Champion Iridium 9044 uses an iridium center electrode and platinum ground electrode to concentrate the spark at the firing point. That design supports consistent ignition performance in engines that call for a REC8WMPB4 plug type, including applications across Lexus, Toyota, BMW, Porsche, Dodge, Jeep, and Subaru platforms. This part cross-references Global Parts Distributors LLC 4673 for the same application.

Common fitment searches for this spark plug include Champion 9044 for Lexus IS300, Toyota Avalon spark plug replacement, and BMW 328i iridium spark plug applications. It also appears in Porsche 911 and Toyota Highlander service listings where the specified plug type and gap match the vehicle requirements.

What It Helps Address

• Rough idle caused by worn spark plug electrodes
• Hard starting from weak or inconsistent spark output
• Misfire conditions related to plug wear or incorrect gap
• Reduced throttle response from degraded ignition performance
• Service replacement needs on vehicles calling for REC8WMPB4

Installation Notes and Tips

Verify the vehicle’s required plug type, seat style, reach, and gap before installation. This plug is listed with a 0.041 in pre-gap, while some fitments note vehicle-specific gap requirements such as 0.035 in, 0.040 in, 0.044 in, or 0.032 in. Confirm the engine application for Lexus IS300, Toyota Avalon, BMW 328i, Porsche 911, and other listed models before service. Use proper torque procedures and inspect ignition coils and boots during spark plug replacement.

Quality Assurance

Champion Iridium plugs are built for precise spark delivery using iridium and platinum electrode materials. The 9044 follows the REC8WMPB4 plug specification and is listed across multiple OE-style applications for consistent service replacement.
