# 7789A - Porsche to Ford Alternator Conversion Kit - Includes Plug, Alternator, and Hardware
For Porsche owners who cannot find a decent replacement for your original Bosch alternator. Our large case 3G series units use extra heavy duty copper bridge rectifiers, the most common component to fail in an alternator. Also, the larger case unit means good output at idle, and lots of mass to absorb heat.
Includes the alternator, easy wiring combo plug, and all the hardware you need to adapt the 3G series alternator in place of your original Bosch unit.
This product is only confirmed to work on 1985 and newer Porsche 928 models with 32 valve option only.
*If you choose an alternator rated more than 140A, you will have to upgrade your battery wiring. Use at least a #4 AWG cable over your existing cables, from the alternator battery post to the battery positive, then from the alternator frame to battery negative.*
