Ignition Coil and Iridium Spark Plugs for Subaru Outback (2010-2011) 3.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2010-2011 Subaru Outback

What it Does: Restores complete primary and secondary ignition performance across all six cylinders to eliminate misfires, rough idle, and unburnt fuel waste.

The Stock Outback Ignition Coil Breakdown

The horizontally opposed EZ36D engine places its cylinder heads in tight proximity to the frame rails, exposing the factory coil-on-plug packs to extreme thermal cycling and trapped engine bay heat. Over time, stock epoxy insulation degrades, resulting in micro-cracks, internal winding resistance shifts, and high-voltage dielectric breakdown under heavy throttle load. Simultaneously, standard factory spark plugs suffer from center-electrode erosion, widening the spark gap and forcing degraded ignition coils to work beyond their saturation capacity.

The Engineering Solution

This 6-cylinder refresh kit features reinforced coil-on-plug assemblies engineered with high-grade internal copper windings and thermal-resistant dielectric resin housings to prevent voltage leakage. Paired with fine-wire iridium spark plugs, the system requires lower secondary ignition voltage to bridge the gap, promoting rapid flame kernel propagation, complete combustion chamber burn, and consistent spark stability up to redline.
