Description
Upgrade your BMW N54 ignition system with high-performance B58 coil technology.
Transform your weak factory N54 coils into powerful, reliable ignition performance with this premium N54-to-B58 Coil Conversion Kit. Engineered for enthusiasts seeking improved spark energy, smoother power delivery, and enhanced reliability, this kit makes upgrading easy and efficient.
Each kit features precision CNC-machined billet aluminum adapter brackets that ensure a perfect fit and long-lasting durability. The plug-and-play harness connectors simplify installation—no cutting, soldering, or splicing required. This complete solution is compatible with BMS High Output B58 coils, OEM BMW B58 coils, and most aftermarket B58 coil options.
When paired with BMS High Output B58 coils (sold separately), your ignition system delivers 2–3 times more energy output than stock N54 coils, resulting in a stronger, longer-duration spark for improved combustion, throttle response, and overall performance.
