How much does it cost to change spark plugs on a Subaru Crosstrek?
Replacing the Crosstrek’s spark plugs typically costs between $180 and $350 at an independent shop, and around $300 to $500 at a dealership. If you do it yourself, parts usually run about $40–$100 for four plugs, depending on the type you choose.
What drives the total price
Price variations come from part types, labor rates, and where you get the service. Here’s a breakdown of the major factors that influence what you’ll pay.
Parts costs
Spark plugs come in several varieties, and the Crosstrek uses four plugs. Material and brand affect price.
- Iridium plugs: roughly $8–$15 each
- Platinum plugs: roughly $6–$12 each
- Copper plugs: roughly $2–$4 each (less common for newer Crosstreks but possible on older models)
- OEM vs aftermarket: OEM plugs may be priced slightly higher, while reputable aftermarket options can save money
Before you read the list, note that four plugs are required for a Crosstrek. The following price ranges are typical for common options:
Conclusion for parts: In most cases, four plugs at retail price will be between about $32 and $60, with higher-end options or OEM parts pushing toward the $60–$100 range in some markets.
Labor costs
Labor is the other major driver. The Crosstrek’s spark plugs are accessible but require some disassembly, which affects time and price.
- Typical time to replace all four plugs: about 1.0–2.0 hours
- Labor rate: roughly $100–$160 per hour, depending on region and shop
- Potential extra charges: if ignition coils or coil boots need replacement, or if the intake manifold must be removed for access
Before you read the list, keep in mind typical shop charges cover both labor and any minor consumables:
Conclusion for labor: Expect roughly $100–$320 in labor at an independent shop, with dealership rates sometimes higher, potentially pushing total toward the $300–$500 range when coils, gaskets, or manifold work are required.
DIY vs professional service
Doing it yourself is usually the cheapest option if you’re comfortable with basic automotive tasks. You’ll pay only the cost of four plugs and any small tools you might need. Professional service adds labor and sometimes diagnostic checks, but it reduces the risk of cross-threading plugs or damaging coil packs.
- DIY parts cost: approximately $40–$100 for four plugs
- DIY time: roughly 1–2 hours, depending on your mechanical experience
- Potential risk: improper torque or cross-threading can lead to costly repairs
Before listing the DIY considerations, note that a Crosstrek with a typical 4-cylinder engine requires four plugs and access is manageable for a motivated DIYer.
Conclusion for DIY: If you have tooling and a comfortable workspace, doing the job yourself can save a significant portion of the total price, provided you buy the right plugs and follow torque specs.
Additional considerations
On some Crosstrek model years, the ignition coils sit on top of each plug (coil-on-plug design). If a coil or boot is worn or damaged, you may see additional costs beyond the plug replacement. It’s also wise to inspect spark plug wires, gaskets, and the general condition of the ignition system while the engine is opened up.
Summary
In practical terms, most Crosstrek owners will pay between $180 and $350 at an independent shop for a four-plug replacement, with dealership estimates often higher due to labor rates. DIY enthusiasts can expect roughly $40–$100 for parts plus their own labor time. Always verify the recommended replacement interval for your exact model year in the owner’s manual, typically around 105,000 miles for many Crosstrek engines, and plan for potential accessory replacements if required by wear or fault codes.
Bottom line: expect a mid-range maintenance cost, with savings available if you tackle the job yourself and if you choose cost-effective plug options that meet Subaru’s specifications. A quick check with local shops can give you a precise target based on your area and model year.
