A 400 Amp Billet Unit for the 2.0L A4

The Mechman unit listed for the 2007-2009 A4 and A4 Quattro with the 2.0L engine is a 400 amp billet alternator. Its billet construction is aimed at drivers who need high current for long stretches, such as a multi-amplifier audio system, a set of driving lights and heated seat covers all switched on during a winter drive. Confirm your year and engine in the vehicle finder above the products before ordering.

Older German sedans also benefit when voltage stays stable, since LED retrofits and aftermarket head units are sensitive to dips during cold starts and short winter trips.

This is one of the Mechman high output alternators shared by several 2.0L cars from the Volkswagen and Audi family, including the Audi TT and TT Quattro and the Volkswagen CC, so A4 owners will find build ideas across those platforms.

Completing the Charging Upgrade

A 400 amp Audi A4 / A4 Quattro high output alternator calls for charging cables that can handle the current. Look at our amp wiring kits and a matching battery from our batteries. For other models, visit the Audi alternators collection.
