03/04 Cobra Big-3


The alternator is only 1 of the 2 critical components that need addressed in your Cobra’s charging system.

Often overlooked, upgrading the factory powers and grounds on your Cobra is as important and required when using a J2Fab unit.

Mechanically crimped, heat shrunk, glued/sealed from J2Fab, this kit is as close to a “bolt in” application specific kit as you will find for your Mustang.

Kit will include everything you need to upgrade the power, ground, and fuses to ensure you are getting the very best performance from your charging system.

When using this kit with a battery relocation, you will use all but one of the power wires. This will take care of everything up front.

When placing your order, please specify in the comments the amperage of your alternator so we can include the proper fuse.

Failure to do so will result in a delay in shipping your product.
