Which Subaru and Saab Models Does This Starter Fit?

This unit is built for non-turbo applications only — the W/O Turbo in the product name is a hard limit. If your engine carries a turbocharger, this is not your part. For the naturally aspirated engines below, it is a direct bolt-in.

• 2004–2011 Subaru Impreza — 2.5L H4 (EJ253), non-turbo, manual or automatic
• 2004–2011 Subaru Forester — 2.5L H4 (EJ253), non-turbo, manual or automatic
• 2005–2006 Saab 9-2X 2.5i — same EJ253 engine and starter geometry as the Impreza wagon
• Select 2004–2009 Subaru Outback / Legacy — 3.0L H6 (EZ30D), automatic transmission

The Saab 9-2X is the fitment most owners miss. The 9-2X 2.5i is mechanically a Subaru Impreza wagon, yet many catalogs misclassify it because of the badge. This unit accounts for the Saab variant's identical EJ253 architecture — same bellhousing pattern, same 23300AA-series starter geometry.

Fitment Matrix and Technical Specifications

Fitment by Model and OEM Cross-Reference

Match your year, engine, and transmission against the matrix. All four OEM numbers share the same starter geometry within these ranges, so one unit covers manual and automatic variants.

The key numbers, straight from the spec sheet.

Why the 9-Tooth Pinion Matters

The EJ253 runs a 10.0:1 compression ratio, and the EZ30 places its own momentary torque demands on the starter pinion as it fires. Both engines ask for real cranking torque on every key-turn, and that is where weak or mismatched units give up first.

The ECCPP assembly uses a precision-ground 9-tooth pinion that mates cleanly with the Subaru flexplate and flywheel ring gear. Generic universal-fit starters often skip that detail, and a mismatched pinion accelerates ring-gear wear — turning a starter swap into a far bigger repair.

Starter Fault Codes: P0615, P0616, P0617

Even the 2004–2011 generation logs starter-circuit problems through standard OBD-II codes. Pull codes before you buy — the code tells you whether the starter, the relay, or a ground strap is the real fault.

P0615 — Starter Relay Circuit Malfunction

An open, short, or high-resistance condition in the starter relay control circuit. Symptoms: no-crank, a single click, or intermittent engagement. Common on high-mileage EJ253 engines where the relay contacts have degraded.

P0616 — Starter Relay Circuit Low

The ECU sees voltage below threshold on the relay circuit. That usually points at a corroded ground strap or a failing ignition switch, not the starter. Test the battery terminals and the engine ground before condemning the starter.

P0617 — Starter Relay Circuit High

Excessive voltage on the circuit — often a solenoid winding short or relay coil feedback. If a new starter clears the code, the old solenoid was the root cause. The ECCPP assembly includes a brand-new, factory-calibrated solenoid, which removes this failure mode from day one.

OEM vs Aftermarket Starters in 2026

Aftermarket starters have closed the quality gap heading into 2026. Tightened ISO 8854:2026 standards mandate longer cold-cranking endurance cycles, a solenoid pull-in voltage tolerance of ±0.3V, and a minimum of 480 hours of salt-spray corrosion testing. ECCPP's manufacturing partners build to these benchmarks.

Price is the other half. OEM Denso units cost 2.5× to 3× more, and dealer parts counters quote $380–$520 for the 23300AA450 or 23300AA560 starter — before labor. To browse related electrical parts in one place, see the Starters, Alternators & ECUs collection on Koeep.

DIY Installation: Tools, Torque, and Time

Swapping the starter on a 2004–2011 non-turbo Impreza or Forester is a driveway job — about 3 out of 10 for difficulty, typically 45–90 minutes. On the EJ253 the starter sits at the top of the engine bay on the passenger side, so most of the work happens from above.

• 10mm, 12mm, and 14mm sockets with extensions, plus a ratchet
• Torque wrench — final torque on the mounting bolts is 37–39 ft-lbs
• Dielectric grease for the electrical connections

Critical safety step: disconnect the negative battery terminal before you start. The ECCPP unit arrives pre-clocked and pre-greased, so there is no extra lubrication, no shimming, and no bench work.
