Construction details are designed to support heat management, resistance to fouling and durability in outdoor power-equipment service.
Designed for the listed ERAYAK generator series to support straightforward replacement when the correct plug code is selected.
The ceramic insulator supports electrical isolation and durability under engine operating temperatures.
Copper-core construction helps transfer heat and supports stable spark-plug operation.
The plated shell helps resist rust and oxidation during normal power-equipment use and storage.
The plug is supplied pre-gapped, but generator maintenance should still follow the model-specific owner’s manual.
Match E6RTC or F7RTC to the generator series and verify the requirement in the owner’s manual.
Check the supplied gap against the manual specification before installation. Do not assume shipping cannot affect the electrode gap.
Start the threads by hand and tighten according to the generator manual to avoid thread or cylinder-head damage.
Service only when the generator is shut down, cool and protected against accidental starting.
Resolve compatibility and installation questions before removing the existing plug.
Select E6RTC for the 2400P Series and confirm the exact generator model in its owner’s manual.
Select F7RTC for the 4500 Series and confirm the exact generator model in its owner’s manual.
It is supplied pre-gapped, but the gap should still be checked against the generator manual before installation.
Incorrect tightening can damage threads, affect sealing or make future removal difficult. Follow the torque procedure in the generator manual.
Inspect and replace it according to the generator’s maintenance schedule, or when inspection shows wear, fouling or damage. Diagnose starting and running issues before assuming the spark plug is the only cause.
Correct compatibility, gap and tightening procedure matter as much as the spark plug itself. Verify the generator model before purchase.
