When This Jaguar Coil and Plug Set May Be Needed

Ignition coils and spark plugs may need inspection when the engine has rough idle, hard starting, hesitation, misfire symptoms, reduced power, poor fuel economy, or a check engine light. These symptoms can also come from plug wires where equipped, wiring faults, fuel delivery problems, vacuum leaks, or compression issues. For code-based review, see Jaguar V6 ignition coil circuit review.

UF435 and SP479 Reference Checks

Compare C2S11480, C2S42673, C2S7928, XR822478, UF435, UF-435, UF435T, GN10327, C808, 1788472, 48924, and COP260 with the original coil.
Compare SP1004 and SP479 with the spark plug specified for the vehicle.
Check connector orientation, coil body, boot length, plug reach, seat type, heat range reference, and gap requirement.
Confirm the package quantity against the number of cylinders being serviced.

Installation and Service Notes

Work on a cool engine, inspect the old spark plugs for fouling, and follow Jaguar-specific service information for torque and gap. If symptoms remain after installation, continue diagnosis by checking wiring, fuel delivery, intake leaks, injector operation, and compression. This BDFHYK set is an OE-style aftermarket replacement, not a factory-branded Jaguar part.

Q: What is included in the package?
A: This product page uses Jaguar UF435 / SP479 reference data. Confirm the package quantity shown on the listing before ordering and compare it with the number of cylinders being serviced.

Q: Which OE or interchange references should I compare?
