This complete ignition system is designed to replace the factory pencil style coils which are prone to failure and incapable of properly supporting the needs of high horsepower applications. The kits all come complete with new ignition coils designed in house and manufactured to our specifications based on the needs and capability of the N54 engine. 

 

Before now the only solutions for the N54 community were all pencil style coils which are incapable (due to size limitations) of producing the same output as larger Ignition Block style coils.  To make the best of the small package the pencil coil has, they are designed for high voltage output but very low current output.  This means the spark will bridge the gap on the spark plug and then disappear.  There is no duration to the spark and in the event the fuel does not ignite (or ignite fully) in that very short period of time you will have a misfire or incomplete burn.

 

Please Note: 

For the OEM location kit, the ignitions coils will not be relocated.

The Aftermarket Manifold location kit is designed for relocation of the ignition coils onto aftermarket inlets.

For the relocation kit on the OEM manifold side, you will need the PR N55 BMW Ignition Kit

Because of the constraint of space to put components in a pencil coil reliable and proven ACDelco ignition coils (PN D585 / LS Truck Coils) paired with short plug wires are used in high horsepower applications everywhere. So why didn’t we just make a kit using these coils since they are the “standard” in many high horsepower applications? 

  • Your car is specifically designed to run “Dumb Coils” and the ACDelco coils are “Smart Coils”

This leaves four options for adapting the car to work with them

  1. Remove the factory DME and replace with Standalone system

      - Very costly & you lose some factory func
