Comparison Insights: Which Coil Pack is Right For Your Crosstrek?

Choosing the best ignition coil for subaru crosstrek often comes down to two factors: the model year and whether you need coils only or a complete kit.

Model Year Matters:
The Subaru Crosstrek underwent ignition system changes around the 2015 model year. If you own a 2013–2014 XV Crosstrek, you will likely need the UF710/UF724 family of coils (like the PHILTOP UF710 or TRQ set). If you own a 2015–2017 Crosstrek or XV Crosstrek GAS, you will need the UF747/UF774 series (like the A-Premium or PHILTOP kits designed for later years). Always double-check your fitment using your specific year and engine size.

Coil vs. Kit:
While replacing just a failing coil (e.g., using the Readair or Autopptimus coils) can fix an immediate misfire, if your vehicle has over 60,000 miles, it’s highly advisable to choose a coil and spark plug kit (like the A-Premium or UF724 kits). Iridium spark plugs in these kits provide substantial benefits, including smoother idle, quicker start-ups, and dramatically longer replacement intervals. For maximum longevity and fuel efficiency, the UF724 kit stands out with its 100,000-mile plug rating.

Focus on Materials:
For the Boxer engine, which runs hot, look for coils that specifically mention high-temperature resistance (like the 140°C rating in the PHILTOP coils) and use high-quality copper windings to ensure efficient voltage transmission under stress.

Final Verdict: The Consensus Picks

Based on performance, material quality, and real-world value, the decision for the best ignition coil for subaru crosstrek depends on your maintenance goal:

Best Comprehensive Upgrade (2013-2014 Models):
The UF724 Ignition Coil Pack and Iridium Spark Plugs Set is the winner. Combining German-imported copper windings with plugs rated for 100,000 miles, this set is an investment in long-term performance and efficiency.

Best Value Kit (2015-2017 Models):
The A-Premium Set of 4 Ignition Coil Pack and Iridium Spark Plugs provides outstanding cost-effectiveness and convenience for the mid-generation Crosstrek. It ensures both your coils and plugs are matched perfectly for the 2.0L engine.

Best Coil-Only Replacement:
The Autopptimus UF747 Ignition Coil is the most highly recommended coil for solving specific performance issues like stalling and rough idling, offering excellent OE-plus quality across the operational range.

Best Ignition Coil For Subaru Crosstrek FAQ

Q1: What are the common symptoms of a failing ignition coil in a Subaru Crosstrek?

A: The most common signs are a rough engine idle, noticeable misfires (especially during acceleration or under load), a decrease in power, and poor fuel economy. Often, the Check Engine Light (CEL) will illuminate, possibly showing codes related to misfires (P030X).

Q2: Is it better to replace all four coils at once, or just the faulty one?

A: While you can replace only the faulty coil, most experts recommend replacing all four, especially if the vehicle has high mileage or if the existing coils are over five years old. Ignition coils age at similar rates, and replacing them as a set ensures uniform performance and prevents sequential failures, providing greater long-term reliability for your Boxer engine.

Q3: How do I know if I need the UF710 (early) or UF747 (later) style coil pack?

A: The main distinction often falls between the 2013–2014 XV Crosstrek (which commonly uses UF710/UF724) and the 2015+ Crosstrek/XV Crosstrek GAS (which often uses UF747/UF774). Always use Amazon’s garage tool or check your original coil’s OE number before purchasing any best ignition coil for subaru crosstrek to guarantee proper plug-and-play fitment.

Q4: Why are Iridium spark plugs included with many of these coil kits?

A: Iridium is a tough, heat-resistant alloy that allows for a much smaller center electrode than traditional plugs. This results in a sharper, more concentrated spark, which enhances fuel efficiency and starting performance. Critically, Iridium dramatically extends the replacement interval for spark plugs, often triple the lifespan of standard copper or nickel plugs.

Q5: Can a faulty ignition coil affect my Crosstrek’s fuel efficiency?

A: Absolutely. A failing coil delivers a weak or intermittent spark, leading to incomplete combustion of the air/fuel mixture. This results in wasted fuel, decreased engine power, and higher emissions. Replacing the failing coil is one of the quickest ways to restore optimal engine performance and fuel efficiency.

Q6: How difficult is it to install the ignition coils on a Subaru Crosstrek?

A: Replacing the coil packs is a maintenance task many DIYers can handle. The coils are typically mounted directly to the valve cover (Coil-On-Plug setup). Since the reviewed products are direct OE replacements, they are designed for simple plug-and-play installation, usually requiring basic tools to remove a few bolts and unplug the harness.

Q7: What are LSI keywords?

A: LSI (Latent Semantic Indexing) keywords are conceptually related terms to the main keyword, such as “Boxer engine,” “fuel efficiency,” “misfire,” “OE replacement,” and “coil packs,” which help search engines understand the full context and relevance of the article.
