A Mercedes ignition coil typically costs between $60 and $250 per coil before labor, with OEM parts and newer coil-on-plug units tending to be at the higher end, plus installation if you don’t replace it yourself.
Understanding what drives the price
Prices vary depending on the specific engine and configuration, as well as the source of the part. The key factors are the part type, brand (OEM vs aftermarket), and the age of the vehicle.
- Part type: coil-on-plug (COP) units for each cylinder vs. a multi-cylinder coil pack can affect price per unit and total cost.
- Brand and source: OEM Mercedes parts are typically more expensive than aftermarket brands (Bosch, Beru, Mahle, etc.).
- Engine and model year: newer or high-performance engines may use specialized COP units that cost more.
- New vs remanufactured vs used: remanufactured or used coils are cheaper but carry different risks and warranties.
- Region and retailer: prices vary by country, store, and whether you’re buying online or in person.
In short, the price you see will hinge on whether you’re buying an individual coil or a full coil pack, and whether you choose OEM or aftermarket parts.
Typical price ranges by configuration
Below are common ranges you’re likely to encounter when shopping for a Mercedes ignition coil. Prices can fluctuate with market conditions and availability.
- OEM ignition coil (single COP unit) for Mercedes-Benz engines: about $120–$250 per coil.
- Aftermarket COP units (Bosch, Beru, Mahle, etc.) for a single cylinder: about $60–$160 per coil.
- Coil packs (multiple cylinders) or OEM-style packs for certain engines: about $200–$600 per pack, depending on the number of coils and the model.
- Remanufactured or used coils: roughly $50–$120 per coil, with varying warranties.
Prices reflect whether you’re purchasing a single coil, a full pack, or an OEM versus aftermarket option, and they can be higher for rare or newer models.
Costs beyond the part: labor and total job cost
Installing a new ignition coil involves labor in addition to the part price. Labor times and rates vary by shop and region, and the total job cost scales with how many coils you replace at once.
- Single-coil replacement (typical for a misfire on one cylinder): roughly 1–2 hours of labor depending on accessibility.
- Multiple coils replaced together: labor cost rises with time but can be more cost-efficient per coil if done at once.
- Combined parts and labor estimate per coil: generally $150–$500 for a single coil replacement, and higher if several coils are replaced or if the job requires additional seals or sensors.
Keep in mind that dealer service may be at the upper end of this range, while independent shops often offer more competitive rates.
Shop smart: tips to save
To minimize costs without compromising quality, consider the following approaches when shopping for a Mercedes ignition coil.
- Compare OEM vs reputable aftermarket brands for the same coil type and vehicle model.
- Check if remanufactured coils come with a warranty and how it applies to your vehicle.
- Ask for a full diagnostic to confirm the exact faulty coil(s) before replacing multiple units.
- Request quotes from multiple shops, including what’s included in the price (labor rate, parts warranty, and disposal fees).
Always verify compatibility with your exact Mercedes model and engine code, and confirm warranty terms before purchasing.
Summary
When budgeting for a Mercedes ignition coil, plan for roughly $60–$250 per coil for the part itself, with OEM parts typically at the higher end. Labor can add $100–$300 or more per coil, depending on engine accessibility and local rates. If you’re replacing multiple coils, total costs will rise, but you may save on labor per coil by performing the service together. Shop around for OEM and reputable aftermarket options, confirm compatibility, and weigh remanufactured versus new parts alongside warranty considerations.
