The Michigan Motorsports 36" Ignition Coil Harness Extension is designed for remote mounting ignition coils on LS2, LS3, LS7, LQ4, and LQ9 engines. This one-piece design eliminates the need to patch together a bracket harness and extension harness, giving your coil relocation a clean, professional look.
 
We offer Coil Relocation Kits for all LS coil styles — matched with the correct coils, harnesses, and brackets — so you can be confident in perfect fitment. We also sell coils, harnesses, and brackets individually.
 
All LS coils are interchangeable and can be used on any LS platform, as long as the correct coil wiring harness and bracket are used. For example, D585 Heat Sink Truck coils can be used on an LS1 that originally had D580 coils, provided the proper harness and bracket are installed.
