A very common modification to clean up the engine bay of any swap is to remove the bulky, unsightly coilpacks from the top of the engine valvecovers. Doing so creates the task of remote mounting the coilpacks, and getting power and signal to them.
 
These 24" long extensions interface between your engine harness and subharness to allow you to place your coil packs virtually anywhere. If you need a longer length, you may contact me directly to place an order.
 
Priced per pair.
