This alternator bracket allows 5.4L DOHC owners the capability of moving the alternator to the left side of the engine. It utilizes the alternator from the 1999-2002 power stroke diesel. Why would you want to do this?
If you are running our 5.4L single plane intake with the integral water crossover it is a necessity to clear the water crossover.

If you are trying to run a positive displacement supercharger, moving the alternator away from the center of the engine greatly simplifies belt routing.

If you do not like the alternator being the central focus of your engine when you open the hood.

When using this bracket it will require that you use the 2003 Cobra
oil cooler. This cooler routes the water outlet below the power
steering pump. It is available under Ford part # F8ZZ6A642BA for about 150.00. The stock oil filter will not clear the rear of the alternator. You will need to run K&N oil filter # 33-2713 or equivalent. You may also use a remote oil filter adapter.

on the left side of the engine. This idler pulley is available through Ford under part # F65Z8678AAA for about 15.00.
