UF618 / 94940 Service Scenarios for Jaguar & Land Rover Applications

Rough Idle or Cylinder Misfire

Inspect the affected spark plug, ignition coil, connector, wiring, boot, and plug well. A misfire code identifies a condition to diagnose and does not prove every coil or plug is faulty.

Hesitation Under Load

Ignition demand increases under acceleration and load. A marginal coil or worn plug may contribute to an intermittent misfire, but fuel, air, sensor, compression, timing, and mechanical conditions should also be checked.

Eight-Piece Ignition Service

The kit contains eight coils and eight plugs. Confirm the exact V8 or other listed engine configuration and required service quantity before treating the package as a complete engine set.

How to Confirm UF618 and 94940 Fitment Before Ordering

Confirm the exact Jaguar or Land Rover model, year, and engine.
Compare UF618, UF637, LR010687, and the listed interchange references with the original coil.
Check connector shape and keying, coil body, mounting point, and boot profile.
Confirm the original spark plug or service information matches 94940.
Confirm required ignition coil and spark plug quantity for the exact engine.

Installation Checks for the UF618 & 94940 Jaguar / Land Rover Kit

Work on a cool engine.
Inspect wiring, connectors, boots, plug wells, oil, and moisture.
Compare every new component with the removed part before installation.
Use vehicle service specifications for spark plug gap and tightening torque.
Recheck stored or returning misfire codes after service.
