ECCPP 4 Ignition Coils with 4 Iridium Spark Plugs for Mercedes-Benz

In this review the ECCPP 4 ignition coils with 4 iridium spark plugs are evaluated for owners of Mercedes-Benz C230 2002 and SLK230 2001-2004 with the 2.3L L4 engine. The bottom line: this kit is aimed at DIY mechanics and independent shops who want a cost-effective way to restore misfire-free running by replacing coils and plugs together. The most persuasive reason to buy is the matched coil-and-plug approach that promises improved spark energy and smoother cold starts compared with worn factory parts.

Key Features

• Vehicle Compatibility: Designed specifically to fit Mercedes-Benz SLK230 2.3L (2001-2004) and C230 2.3L (2002), simplifying correct selection for those models.
• OE Replacement Numbers: Replaces common OEM part numbers including 0001501780 and 0001502880, which helps ensure a direct-fit swap into the factory ignition system.
• Higher Energy Output: ECCPP states the coils and plugs deliver about 15% more energy than OE coils, which can improve combustion consistency and throttle response.
• Durable Construction: Built with high conductive copper wire and high-dielectric epoxy, the components aim for corrosion-resistant connections and a longer service life.
• Matched Set: Shipping coils and iridium spark plugs together encourages replacing both items at once to reduce misfire risk and restore fuel economy.

Who It's For

This kit is a good fit for Mercedes owners who are comfortable with basic engine work or who use an independent shop and want a complete coil-plus-plug service. It targets vehicles with the specific 2.3L L4 engine where failing coils or worn plugs cause misfires, hesitation, poor mileage or CEL warnings.

It is less suitable for owners who prefer OEM-branded parts from the vehicle manufacturer or for those who need guaranteed long-term factory warranties; a dealer-sourced coil or plug may be a better fit for those priorities.

Pros & Cons
