ECCPP UF680 4 Ignition Coils with 4 Iridium Spark Plugs - Reliable

In this review the ECCPP UF680 kit is evaluated for drivers who need a full ignition service on compatible 2.0L and 2.5L L4 engines. The bottom line: this set of four ignition coils and four iridium spark plugs offers a clear value proposition for owners of Camaro, Colorado, Impala, Malibu and various Buick and Cadillac models because it replaces multiple OEM part numbers and aims to restore smooth idle and eliminate misfire codes. The reviewer found the kit to be a practical, cost-effective alternative to factory parts when fitment is confirmed.

Key Features

• Direct fit compatibility: The kit lists multiple OEM replacements such as UF680, 12652405 and 12687140, making it suitable for a range of 2.0L and 2.5L L4 vehicles when the fitment matches.
• Combined service parts: Including four coils and four iridium spark plugs lets you replace coils and plugs together to improve cold-start performance and reduce misfire risk.
• Improved energy output: ECCPP states the coils deliver about 15% more energy than OE coils, which can help restore throttle response and combustion stability.
• Durable construction: High conductive copper wire and high dielectric epoxy with corrosion-resistant connections are designed to extend service life under typical driving conditions.
• OEM-level reliability claim: The set is built to achieve or exceed OE specifications, which aims to reduce check engine light triggers tied to ignition faults.

Who It's For

This kit is best for owners of Chevrolet Camaro 2016-2018, Colorado 2015-2018, Impala 2014-2019, Malibu 2013-2018 and compatible Buick and Cadillac models with 2.0L or 2.5L L4 engines who want a full ignition refresh without paying dealer prices. A DIYer comfortable verifying part numbers and replacing plug and coil packs will find the included four coils and four plugs convenient.

Those who should look elsewhere include vehicles outside the listed engine families or owners who require dealer-branded parts for warranty reasons. Also confirm exact OEM part numbers before purchase since fitment depends on specific model years and engine variants.

Pros & Cons

Pros
