Product Number: 12685N
The WAI 12685N is a brand-new 12V 33A alternator. It is built to Bosch IR/EF specification, designed as a direct replacement for original-equipment units from Bosch, Remy, Marelli, Iskra / Letrika, Mahle, and Magneti Marelli. With 49 OE cross-references covering a broad range of original fitments, it is a well-supported aftermarket choice for workshops and restorers sourcing a reliable alternator replacement.
Constructed to IR/EF (internally regulated, externally fan-cooled) design, the 12685N delivers a regulated 12-volt output at 33 amperes with clockwise rotation — matching the performance envelope of the original-equipment units it replaces. Being supplied brand new rather than remanufactured means there is no core charge and no uncertainty about internal wear condition, making it straightforward to fit and commission.
This alternator carries OE cross-references from a wide aftermarket network. Bosch references include 0 120 339 526 and Bosch Service 0 986 033 070. Remy Europe lists it as DRA3070, Marelli and Magneti Marelli as MAR846 and MAR 846 respectively, Iskra / Letrika under 11201062, IA0062, and AAG1307, and Mahle as MG 371 — among 49 cross-references in total.
