This bracket mounts the 3 coils remotely to the strut tower next to the C 500 connector or on the inner fender when the battery is moved.
This moves the coil pack in one of the coolest places in the engine compartment. Custom spark Plug wires will have to be made by the builder. The wire kits can be purchased at your local auto parts store. V8 wire kits seem to work well as they are longer than the 6 cyl kits.
