Comparison Insights on Choosing the Best Ignition Coil For Subaru Impreza

Choosing the right coil depends heavily on your specific Subaru model year and engine type, as fitment varies drastically between generations.

If you own an early 2000s WRX (2.0L EJ205), the DrCax UF480 is the necessary choice due to its specific engineering requirements for turbocharged performance. Standard coils won’t provide the same reliability under boost.

For naturally aspirated (NA) Imprezas built before 2011, the SCITOO UF-538 offers the widest, most cost-effective coverage, making it a great general maintenance part for older cars.

If your Impreza is a newer model (2013-2015), the A-Premium Set of 4 is unbeatable value. The included Iridium spark plugs make this purchase an investment in superior long-term engine efficiency, not just a repair.

Finally, for precise replacements on the 2011 and 2012 transitional years, A-Premium and SCITOO provide reliable single-coil options (UF-625 and UF-664 respectively), tailored for those specific engine codes.

Final Verdict: Which Coil Gets the Gold?

Determining the single “best” coil is impossible without knowing your model year, but we can highlight the top performers by category:

Best Ignition Coil For Subaru Impreza FAQ

How do I know if my ignition coil needs replacing?

The most common symptoms of a failing ignition coil, or “coil pack,” include engine misfiring (a jerky or sputtering feeling, especially under acceleration), poor fuel economy, rough idling, lack of power, and, critically, the check engine light illuminating, often storing specific misfire codes (P0301, P0302, etc.). Since the Boxer engine configuration makes accessing spark plugs tricky, diagnosing a failing coil early is vital.

Is it necessary to replace all four ignition coils at once?

Not always. If only one coil has failed, you can replace that single faulty unit. However, since all the ignition coils have experienced the same wear and tear, experts often recommend replacing the full set, especially on high-mileage vehicles. If one has failed, the others are usually close behind. Replacing the whole set ensures consistent performance across all cylinders.

What is the typical lifespan of an ignition coil on a Subaru Impreza?

The lifespan varies significantly depending on driving conditions and engine maintenance, but factory or high-quality aftermarket coil packs should last between 80,000 to 100,000 miles. Using premium spark plugs (like Iridium) can help prolong the life of the coils by reducing the required voltage output.

Are aftermarket ignition coils reliable for my Impreza WRX?

Yes, provided they meet or exceed OE specifications. For turbocharged engines like the WRX’s EJ205, it is crucial to use coils specifically designed for high-output environments (like the DrCax UF480). High-quality aftermarket suppliers understand the demands placed on performance ignition systems and build reliable components.

What is the difference between a naturally aspirated (NA) and a turbocharged coil pack?

Turbocharged engines operate at higher cylinder pressures and temperatures, requiring the coil pack to generate a much stronger spark to overcome this increased resistance. Turbo coils are typically more robustly constructed and designed to handle higher heat dissipation and stronger current, which is why cross-referencing the correct OE part number is essential when choosing the best ignition coil for subaru impreza.

Can I replace the ignition coils myself?

Replacing ignition coils on a Subaru Impreza is a relatively straightforward DIY job, especially if you have basic mechanical skills. The coils are typically bolt-on units located directly above the spark plugs, often secured to the valve cover. The main challenges are accessing the units due to the compact Boxer engine layout and correctly seating the electrical connectors. Always disconnect the battery before starting work.
