Midnight Motorsports B58 Coil Conversion Kit
Unleash the full potential of your BMW with our Complete B58 Coil Conversion Kit, engineered for ultimate performance, reliability, and ease of installation.
Designed with precision using CAD-modeled, CNC laser-cut sheet metal brackets, our kit offers a direct fit for N54, N55, and S55 engine platforms. Every component has been developed in-house, from our proprietary conversion coil boots to our plug-and-play wiring adapters—ensuring seamless integration and consistent performance.
Our proprietary coil boots are built to accept factory-style spark plugs, and through rigorous testing, we’ve found that a 0.025” plug gap delivers optimal performance across everything from stock setups to aggressively tuned builds. For best results, we recommend NGK #97506 spark plugs.
Whether you're chasing horsepower or just want smoother drivability, our B58 Coil Conversion Kit delivers modern ignition performance for your turbocharged BMW.
