Commonly associated with misfires, rough idle, and general loss of power, factory ignition coils are prone to failure after consistent heat exposure. In addition to these issues, factory ignition coils prove inefficient in high-performance applications. While there are a plethora of kits claiming to solve these issues, none perform as well as B58 ignition coils. 

Supporting well over 1000 WHP, B58 ignition coils are truly the only choice for any enthusiast looking to push the limits of their N54. These ignition coils are capable of producing 2x the spark output of factory coils, while also providing a longer spark duration. Unlike other N54 ignition upgrades, B58 coils are a coil-on-plug design, eliminating the need for bulky remote-mount brackets and plug wires. In short, this kit provides the best performance while maintaining factory simplicity. 

Features: 

• Optimized for elevated boost levels without modification to spark plug gaps
• Significantly improved spark duration and strength
• Improved power and engine idle

To mount the ignition coils, Midnight Motorsports engineered a CAD-designed, CNC-machined sheet metal bracket that provides seamless integration and ample clearance for top-mount turbocharger setups. The kit is designed around their proprietary conversion coil boots which allow for utilizing factory spark plugs with a standard 0.031" gap. Finally, high-quality conversion harnesses are included to merge these coils with your factory connectors. 

Kit Includes:

• CNC-machined aluminum bracket
• 6x high-performance B58 ignition coils available in red, blue, or black finishes
• 6x factory-fit boots
• 6x adapter harnesses
• 6x torx-screws used for mounting the coils to the aluminum bracket

Realize increased spark energy and duration as well as improved driveability and performance with the Midnight Motorsports B58 ignition coil conversion kit.
