KAC Alternator 11070N

For VW owners replacing an alternator, this KAC unit is listed for select Tiguan, GTI, CC, Eos, and Jetta applications. Its 150-amp rating and 12V specification make it a direct candidate to compare with the original unit, not a universal replacement for every vehicle in those model lines. It’s a great fit if you can match your car’s year, engine, and alternator reference number to the listed details. If you prioritize a simple year-and-model match over checking the original part, take extra care before ordering.

Where it shines

The useful detail here is the combination of named VW fitments and replacement references. The listing covers 2009–2016 Tiguan, 2008–2014 GTI with CBFA/CCTA engine design, 2009–2016 CC 2.0L, 2009–2016 Eos, and 2012 Jetta GLI, TDI, and TDI Premium. It also gives a 150-amp output, 12V voltage, clockwise rotation, an SC6 pulley class with six grooves, an IR/IF regulator/fan type, and a 12 o’clock plug clock. Those details give you more to compare than a model name alone.

Picture a repair where the old alternator is already out and you can read its label: matching one of the supplied reference numbers, such as 06B903016AF, 06B903016AA, or 06B903016P, is a more useful check than relying only on “fits Tiguan.” The listing describes a plug-and-play design with no modification or drilling, and says the unit is manufactured to meet or exceed OE standards. Treat those as product claims, though, the supplied information doesn’t identify a warranty or provide independent test results.

What to know

Fitment is the main decision point. A vehicle can fall within a listed year range and still need a particular engine or alternator configuration, so compare the complete application and reference number with the part being replaced. If you’re checking the pulley setup, compare the original unit’s six-groove pulley and plug orientation, a model-year match alone is not enough without that measurement. It may not suit you if you can’t confirm the vehicle details or need a replacement for an application that isn’t listed.

The part-number list is extensive, which helps when a number on the original unit is readable, but it can also make a quick glance misleading. Check the exact code rather than assuming similar-looking numbers are interchangeable. Compared with choosing a replacement from vehicle year alone, matching the label and the listed electrical and pulley details takes another step but reduces guesswork. The listing also mentions shock, abrasion, and fatigue testing, without providing test methods or results.

Best use cases

This alternator makes most sense for a repair where the vehicle and removed unit can both be identified before purchase. For example, a technician or careful DIYer can compare the old part’s label and pulley arrangement with the listed references and specifications, then assess whether the application matches. That is a more reliable approach than buying by a broad model name when engine variants or part numbers may matter.

If your priority is a listed 150-amp replacement with stated pulley and plug details, this gives you concrete specifications to check. If you prefer a part selected solely by a broad vehicle description, the fitment list may require more verification than you want.

Is it worth it?

It’s worth considering when your VW application appears on the list and the original alternator’s reference number and configuration line up with the supplied details. The 150-amp rating, six-groove pulley, and 12 o’clock plug clock help make that comparison specific. The trade-off is that the broad year ranges do not, by themselves, prove compatibility, and the product information doesn’t establish fitment beyond the applications and references it names. Buy it when those details match, choose a different route if you can’t verify the application or need a confirmed fit for an unlisted vehicle.
