ECCPP Ignition Coil Coils & Iridium Spark Plugs UF741 8pcs

In this review the ECCPP ignition coil and iridium spark plug kit is evaluated for Mercedes-Benz V6 and V8 models. The bottom line: this 8-piece set of ignition coils with matching iridium plugs is best for owners who need a full-bank replacement to address misfires, rough idle, or loss of power after long use. The reviewer found the kit easy to install and effective at restoring smoothness on compatible models, though some buyers have reported early failures so durability should be monitored.

Key Features

• Full kit: Includes 8 ignition coils and 8 iridium spark plugs so the entire cylinder bank can be serviced at once for consistent performance.
• Wide fitment: Labeled to fit many Mercedes-Benz models including C300, C350, CL550, CL63 AMG, CLS550, E350 and others for straightforward compatibility checks.
• Reference compatibility: Matches reference numbers UF-741, 2769060501 and NGK95875 to help verify correct replacement parts for the vehicle.
• Restore drivability: Replacing worn coils and plugs is likely to reduce misfires, improve starting, and regain lost power and fuel economy.
• Ease of installation: Customers report the coils and plugs fit as expected and install without modification, saving time during a full-bank service.

Who It's For

This kit is aimed at Mercedes-Benz owners whose vehicles match the listed fitment and who are experiencing ignition-related symptoms after roughly 80,000 km or more, including hard starting, excessive cranking, reduced power, or increased fuel use. It is also appropriate for technicians or DIYers who prefer to replace all coils and plugs at once to avoid mixing new and old components.

Those who should look elsewhere include owners of vehicles not listed in the compatibility chart and buyers who prioritize long-term OEM durability above initial cost savings; some users reported premature failures and may prefer factory-branded coils if longevity is the highest priority.
