Product Information


This kit is for BMW N54 engines with the M18 Performance valve cover ONLY. Please see our other kit if you have a stock valve cover or a Vargas Turbo valve cover.

Check out our ignition coil testing methods and results here!

Compared to the stock N54/N55 ignition coils the B58 coils are capable of producing 2.3x the energy output while providing a longer spark duration than the Precision Raceworks N54/N55 coils. 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. To mount the B58 coils onto the N54 engine we've developed a billet aluminum bracket that's Made in the USA. In addition to excellent fitment, our N54 Ignition Coil Kit with coils fitted weighs only 3.9 lbs. That's 47% less than the Precision Raceworks kit. To make installation easier we've designed plug and play connectors that are made of nylon and Made in the USA. To keep installation clean we've added cut outs for passing the coil harness through and radius's have been chamfered on both sides.

  • Made in the USA billet aluminum coil bracket
  • Plug & Play Connector harness made and assembled in the USA (if selected above for purchase)
  • All kits include mounting hardware

NOTE: KITS DO NOT COME WITH B58 COILS, you will need to provide those yourself. The B58 ignition coils (OE Part #'s: 12138643360, 12138678438, 12138647463, 12137619385) are typically $36 - 42/each and are available from FCP Euro with their lifetime warranty. If you're feeling cheap I've seen sets of used coils on ebay/forums for around $150.
