UF747 / 93501 Service Scenarios for Listed Subaru Applications

Rough Idle or Cylinder Misfire

Inspect the affected ignition coil, spark plug, connector, wiring, boot, and plug well first. Fuel-delivery faults, intake leaks, sensor issues, compression, timing, and other mechanical conditions can create similar symptoms.

Hesitation During Acceleration

A marginal ignition component may become more noticeable under load. Confirm the affected cylinder and component condition before replacement.

Four-Cylinder Ignition Maintenance

The 4+4 package provides a matched-count service option for a confirmed listed four-cylinder application, but exact engine and powertrain fitment must be checked first.

How to Confirm UF747 and 93501 Fitment Before Ordering

Confirm the exact Subaru model, year, engine displacement, and powertrain shown in the application list.
Compare UF747, 22433AA700, 22433-AA70A, 22433-AA70B, 22433-AA730, or the applicable listed reference with the original ignition coil.
Check connector shape and keying, coil body, mounting area, and boot profile.
Confirm 93501 / LKAR7BIX-11S against the removed spark plug or vehicle service information.
For 2016 Impreza, confirm the exact engine and original coil reference before ordering rather than relying on model year alone.

Installation Checks for the UF747 & 93501 Subaru Kit

Work on a cool engine and keep debris out of the spark plug wells.
Inspect wiring, connectors, boots, plug wells, oil, and moisture.
Compare every new ignition coil and spark plug with the removed component before installation.
Use the exact vehicle service specification for spark plug gap and tightening torque.
Verify connector seating and recheck stored or returning misfire codes after service.

Important: These are BDFHYK OE-style aftermarket service components, not factory-branded Subaru parts. Exact engine and OE-reference confirmation is required for mixed-application model ranges.
