DJI D12000iE F7RTC spark plug gap and maintenance

DJI D12000iE Spark Plug Guide: F7RTC Gap, Cleaning, Torque & Replacement

September 17, 2026

The D12000iE v1.2 guide specifies the original spark-plug model, electrode gap and final tightening torque. These details are specific to this manual revision and differ from some other DJI generator models.

Quick Answer: The original D12000iE spark plug is F7RTC. Remove it only after the generator has cooled completely. Replace it if the insulator or sealing gasket is broken. Clean deposits with a stiff wire brush, set the gap to 0.6-0.8 mm, hand-thread it two to three rotations and tighten to 20-24 N·m.

D12000iE F7RTC spark plug gap 0.6 to 0.8 millimeters — The manual marks the 0.6-0.8 mm electrode gap and places spark-plug service directly beneath the spark-arrestor procedure.

Remove and inspect the F7RTC plug

Stop the generator and let it cool completely. Use the dedicated spark-plug socket supplied with the generator. Replace the plug immediately if the insulator or sealing gasket is broken.

Clean deposits

Remove carbon or other deposits with a stiff wire brush. Deposits can affect ignition quality and should be removed before the gap is measured.

Set the electrode gap

Adjust the electrode to a standard range of 0.6-0.8 mm. DJI states that correct gap and a deposit-free plug are required for proper engine operation.

Install and torque

Thread the plug into the engine by hand for two to three rotations, then continue tightening with the dedicated socket. The recommended torque is 20-24 N·m. A loose plug can cause overheating; over-tightening can damage engine threads.

The exact customer-facing catalog handoff is the DJI Agras D12000iE / D12000iEP Generator Spark Plug.

D12000iE F7RTC spark plug 300 hour one year service interval — Spark-plug service belongs to the 300 operating hours / 1 year maintenance group.

If spark-plug service does not resolve ignition symptoms

Do not assume every no-start condition is the spark plug. The D12000iE catalog includes separate ignition components and engine-build variants. Where diagnostics identify the coil path, the D12000iE Generator Ignition Coil is an active product page. Verify the generator build and diagnostic evidence before replacement.
