Fitment:

This is a direct fit high-output alternator for the 2015-2016 Audi A3 2.0L. This alternator is a custom built alternator made with custom fabricated brackets that are laser cut to precision. With our teams dedicated innovation, we have been able to design custom brackets for direct fitment.

Plug:

This high-output alternator comes with a 14.8 GM Style Regulator with a pigtail wiring harness. The pigtail plugs directly into the alternator, and you’ll have to wire the pigtail into the factory wiring.

NOTE: If you require charging at a certain voltage setpoint, we offer a selection of different voltage regulators that you will need to purchase with the alternator for it to be installed. View our Regulator Options Here.

Pulley:

This alternator also comes with a smaller pulley, which causes it to spin faster than a larger pulley. This can help the alternator produce its maximum output. With a smaller pulley, it is required to install a 1/2" - 1" shorter belt.

See this Blog Article for assistance in finding the correct shorter belt.
