Nexsys Motorsports’ B58 Ignition Coil Kit for BMW N55 & S55 engines.

Check Nexsys’ ignition coil testing methods and results here!

Compared to the stock N55 and S55 ignition coils, the B58 coils are capable of producing 2.3x the energy output while providing a longer spark duration than aftermarket coils available. The B58 coils are a coil on plug design that removes the need for additional spark plug wires and utilizes the same mounting location as the stock coils, providing excellent clearance for top mount turbo setups and all of the original componentry. To mount the B58 coils onto the N55 & S55 engine, Nexsys have developed billet aluminium brackets, made in the USA. The N55 & S55 Ignition Coil Kit with coils fitted weighs only 3.0 lbs – that’s over 50% less than the popular alternative kits. To make installation easier, Nexsys designed plug and play connectors that are made of nylon in the USA. This kit comes with new ignition coil boots that are longer than the stock boots. The stock engine cover fits with this kit.

3 x Made in the USA billet aluminium coil brackets

This kit fits all N55 & S55 engines including the early E-series cars.
