Material & Construction
Built for Reliable Ignition
Construction details are designed to support heat management, resistance to fouling and durability in outdoor power-equipment service.
Purpose-Matched Replacement
Designed for the listed ERAYAK generator series to support straightforward replacement when the correct plug code is selected.
Heat-Resistant Insulation
The ceramic insulator supports electrical isolation and durability under engine operating temperatures.
Improved Heat Dissipation
Copper-core construction helps transfer heat and supports stable spark-plug operation.
Outdoor Corrosion Resistance
The plated shell helps resist rust and oxidation during normal power-equipment use and storage.
Before Installation
Three Checks Before You Fit the Plug
The plug is supplied pre-gapped, but generator maintenance should still follow the model-specific owner’s manual.
Confirm the Plug Code
Match E6RTC or F7RTC to the generator series and verify the requirement in the owner’s manual.
Verify the Gap
Check the supplied gap against the manual specification before installation. Do not assume shipping cannot affect the electrode gap.
Use the Correct Torque
Start the threads by hand and tighten according to the generator manual to avoid thread or cylinder-head damage.
Maintenance & Generator Safety
Service only when the generator is shut down, cool and protected against accidental starting.
- Turn off the generator, disconnect all loads and allow the engine to cool before service.
- Remove the spark-plug boot before working around the plug or engine.
- Keep dirt and debris from falling into the spark-plug opening.
- Never run indoors.
- Never run in a garage.
- Never run near open windows.
- Always operate outdoors with proper ventilation.
Buyer Questions
Spark Plug FAQ
Resolve compatibility and installation questions before removing the existing plug.
Which spark plug fits the ERAYAK 2400P Series?
Select E6RTC for the 2400P Series and confirm the exact generator model in its owner’s manual.
Which spark plug fits the ERAYAK 4500 Series?
Select F7RTC for the 4500 Series and confirm the exact generator model in its owner’s manual.
Is the spark plug ready to install?
It is supplied pre-gapped, but the gap should still be checked against the generator manual before installation.
Why should tightening torque be checked?
Incorrect tightening can damage threads, affect sealing or make future removal difficult. Follow the torque procedure in the generator manual.
When should a generator spark plug be replaced?
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.
Choose by Plug Code. Install by the Manual.
Correct compatibility, gap and tightening procedure matter as much as the spark plug itself. Verify the generator model before purchase.

Spares for the ERAYAK 2400P generator. Cheap insurance. There are times when a generator is a nice to have toy.There's a reason ERAYAK includes a spark plug socket as the standard issue tool with their generators. Best to have a spare spark plug to go with it...
