Original BMW Low-Pitch Horn for BMW E46 3 Series 323i, 325i, 328i, and 330i (1999–2006)

The Original BMW low-pitch horn is the deeper-toned horn for the E46 3 Series and fits 1999–2006 323i, 325i, 328i, and 330i models along with their coupe and xi versions. BMW names this part Horn, low pitch, and gives its weight as 248 g, or about half a pound. Production of this number began in November 1997, and BMW still supplies it today. It is sold individually as one horn. An electric horn produces sound when current through its coil moves a metal diaphragm. A deep tone paired with a higher tone produces the two-note sound most drivers expect from a European car.

Original BMW Parts carry a 24-month parts warranty.

This number replaces the earlier 61-33-6-905-423. BMW marks the change as exchangeable retrospectively, so the current horn also fits cars that left the factory with the older part. Parts cross-reference data links this horn to 61-33-8-375-493 as well. BMW identifies this part specifically as the low-pitch horn, so check that the horn you are replacing on your car is the low-tone unit and not its higher-pitched partner.
