Ignition Coil for BMW, Peugeot, and Mini Cooper R56 with N12 Engine
Overview
The ignition coil is a critical component in the ignition system of internal combustion engines, responsible for converting the battery’s low voltage into the high voltage needed to ignite the air-fuel mixture in the engine’s cylinders. This specific ignition coil is designed for use with the BMW N12 engine, which is commonly found in various Mini Cooper R56 models, as well as select Peugeot and BMW vehicles.
Compatibility
This ignition coil is compatible with the following vehicles:
- Mini Cooper R56 models (2007–2010) equipped with the N12B14A or N12B16A engines
- Selected Peugeot 207, 308, 3008, and 5008 models with shared PSA-BMW engines
- Certain BMW 1 Series (E81/E87) and 3 Series (E90/E91) with 1.4L or 1.6L N12 engine configurations
Before purchasing, always verify your vehicle’s engine code and production year to ensure proper fitment.
Design and Construction
The ignition coil features a compact pencil-style design that integrates directly onto the spark plug, eliminating the need for traditional spark plug wires. It includes a durable thermoplastic housing that resists heat and vibration, ensuring longevity and stable performance in harsh engine environments.
Key construction highlights:
- High-output copper windings for reliable voltage conversion
- Heat-resistant epoxy resin for better insulation and coil longevity
- Precision-fit rubber boots to prevent moisture intrusion and electrical arcing
Performance Features
- Optimized Spark Delivery: Ensures consistent combustion for smoother engine operation
- Improved Fuel Efficiency: With precise ignition timing, it aids in better fuel economy
- Reduced Misfires: A faulty coil can cause engine misfires, poor acceleration, and rough idling—this replacement restores full ignition function
- OEM-Equivalent Quality: Meets or exceeds original manufacturer specifications for fit and performance
Installation and Maintenance
Installation is straightforward and typically involves removing the engine cover, unplugging the electrical connector, and pulling the old coil straight out. Always replace ignition coils in full sets for optimal engine performance. It is recommended to inspect and possibly replace spark plugs at the same time.
