ECCPP UF522 8 Ignition Coils with 8 Iridium Spark Plugs - BMW Fitment

In this review of the ECCPP UF522 kit, the bottom line is simple: it is a practical, budget-friendly replacement pack for owners of several BMW V8 models and the Morgan Aero 8 who need a full set of coils and plugs at once. The package includes eight ignition coils and eight iridium spark plugs, which makes it a straightforward choice for a full ignition refresh. It is best for DIY mechanics and independent shops that value parts compatibility and ease of installation over premium OE pricing.

Key Features

• Complete kit: The set contains eight ignition coils and eight iridium spark plugs so a full ignition bank can be serviced in one job without sourcing parts individually.
• Vehicle fitment: Designed for specific BMW V8 models and the Morgan Aero 8, the kit lists compatible chassis and years so buyers can confirm fit before purchase.
• OE cross references: Coils reference several OE numbers such as UF522 and related codes, which helps identify these as direct replacements for older or damaged units.
• Improved starting: ECCPP states the coils deliver fast starting and stable spark, which can reduce misfires and make cold starts more reliable when the unit is functioning correctly.
• Fuel efficiency potential: Replacing worn coils and plugs in a matched set can restore efficient combustion and may reduce fuel use compared with a misfiring or weak ignition bank.
• Plug gap set: The iridium plugs are specified with a 0.040 in gap, removing guesswork for correct plug spacing during installation.

Who It's For

This kit is aimed at BMW owners with V8 engines (E53 X5, E60 545i, E63/E64 645Ci, E65/E66 745i/745Li) and owners of the Morgan Aero 8 who need to replace an entire ignition coil bank and spark plugs at once. It is a good fit for DIYers comfortable with basic engine work and independent mechanics who want a cost-effective alternative to single OE coils.

Those who rely on dealership warranty coverage, demand factory-branded parts, or require long-term proven durability from an OEM supplier may want to look elsewhere. Also, buyers who have experienced repeated early coil failures in any aftermarket line should consider higher-end branded coils with extended warranty options.
