Product Details

NGK’s Laser Iridium High Ignitability line is aimed at vehicles that require precise ignition characteristics and OE-style durability. Part number 94697, also identified as DF5B-8A, is specified for select Lexus NX300h, Lexus ES300h, Toyota Avalon, Toyota RAV4, and Toyota Camry applications. The plug’s iridium tip and dual fine electrode layout help maintain a focused spark kernel, while the copper core supports heat transfer under normal operating conditions. This part cross-references NGK 94697 for the same application.

What It Helps Address

• Hard starting caused by worn spark plug electrodes
• Rough idle from degraded ignition performance
• Misfire conditions related to plug wear or incorrect gap
• Reduced fuel economy from inconsistent combustion
• Loss of throttle response in high-mileage ignition service intervals

Installation Notes and Tips

Verify engine application by year, make, model, and OE spark plug specification before installation. This plug is listed with a 0.032 in. pre-gap and a flat seat, so confirm the engine calls for those specifications before use. For best results, inspect coil boots, ignition coils, and plug wells during service, and follow the vehicle manufacturer’s torque procedure.
