• Copper core center electrode for stable heat transfer
• Nickel center and ground electrode tip materials
• 0.036 pre-gap for OE-style service replacement
• 5,000 ohm resistance for ignition system noise control

Detailed Description

NGK 6773 is engineered as a standard replacement spark plug for engines that specify a copper-core, nickel-tip design with a heat range of 5. The flat seat, 14 mm thread diameter, and 0.75 reach make it suitable for many older and serviceable ignition systems where correct plug geometry matters. For maintenance on vehicles such as Honda Civic and Toyota Corolla, using the correct heat range and gap helps preserve smooth starting, idle quality, and combustion consistency. This part cross-references Bosch 7905 and Autolite 65 for the same application.

What This Spark Plug Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Misfire conditions related to plug wear or incorrect gap
• Reduced fuel economy from incomplete combustion
• Loss of throttle response from weak ignition performance

Installation Notes and Tips

Verify the engine calls for a 14 mm, flat-seat spark plug with a 0.75 reach and heat range 5 before installation. Check the gap against the engine specification before use, even though the plug is pre-gapped at 0.036. Inspect plug wires or coil boots for wear, and apply proper torque during installation to avoid thread damage or sealing issues. For Honda Civic and Toyota Corolla service, confirm the exact engine code and ignition specification in the vehicle catalog before replacing plugs.
