FAQ

Q: Is FW-C-D3F-B compatible with all Subaru EJ-series engines?
A: Yes. The Furukawa FW-C-D3F-B 3-pin 2.3mm ignition coil connector is used across EJ20, EJ25, and related Subaru boxer engines. It is also used on FA20-powered BRZ/GR86. Verify the connector on your specific coil before ordering.

Q: What is the difference between FW-C-D3F-B and FW-C-3F-B?
A: FW-C-D3F-B is the ignition coil-specific variant with a different housing profile optimized for coil-on-plug applications. FW-C-3F-B is the standard 3-pin Furukawa waterproof connector used for general sensor applications. They are not interchangeable.

Q: What terminals are compatible?
A: Furukawa Electric 2.3mm series female terminals for 0.5–1.25mm² (AWG 20–18) wire. Terminals are sold separately.
