Product Details

NGK is a long-standing OE spark plug supplier with broad coverage across domestic and import vehicles. Part number 6290, also identified as PFR6H-10, is engineered for vehicles that specify a platinum plug with a .040 inch pre-gap and flat-seat configuration. This makes it a practical replacement for routine ignition service on Saab 9-5, Saab 9-3, Lexus ES300, Toyota Camry, Honda Civic, and related applications where the factory specification calls for this plug design.

This part cross-references AMS Automotive 4508 and Catco 4707 for the same application.

Common Issues This Part Can Address

• Rough idle caused by worn spark plug electrodes
• Hard starting from weakened ignition performance
• Misfire conditions related to aged plugs
• Reduced fuel economy from inconsistent spark delivery
• Loss of throttle response from degraded combustion efficiency

Installation Notes and Tips

Verify the engine’s required plug specification before installation, including thread diameter, reach, seat type, and gap. This plug is listed with a .040 inch pre-gap for many applications, while some fitments note a .044 inch gap requirement; confirm the vehicle-specific service data before use. Inspect the ignition system, coil condition, and plug wells during service, and follow the manufacturer’s torque specification for the engine.
