UF287 / 4704 Service Scenarios for Subaru 3.0L & 3.6L H6

Rough Idle or Cylinder Misfire

Inspect the affected coil, spark plug, connector, wiring, and plug well first. Oil, moisture, fuel-delivery issues, intake leaks, sensors, compression, timing, and other mechanical conditions can produce similar symptoms.

Hesitation During Acceleration

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

Six-Cylinder Ignition Maintenance

The 6+6 package provides a matched-count service option when the exact listed H6 application and original ignition components are confirmed.

How to Confirm UF287 and 4704 Fitment Before Ordering

Confirm the exact Subaru model, year, and 3.0L or 3.6L H6 engine shown in the fitment table.
Compare UF287 and the listed 22433AA-series references with the original ignition coil.
Check the 3-pin connector, keying, coil body, mounting area, and boot profile.
Confirm spark plug reference 4704 against the removed plug or service information.

Installation Checks for the UF287 & 4704 Subaru H6 Kit

Work on a cool engine and keep debris out of the plug wells.
Inspect wiring, connectors, boots, plug wells, oil, and moisture.
Compare every new component with the removed part 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. Continue diagnosis if symptoms remain after ignition service.
