WAI 14204N Alternator

Overview

WAI 14204N is a new alternator built for BMW applications that require a Denso-style 210 amp charging unit. It is engineered to deliver the electrical output needed for modern vehicle loads while using new components rather than remanufactured parts.

This alternator fits BMW 320i, 328i, 528i, X3, X4, and related applications with Denso IR/IF 210 amp specifications. The WAI 14204N is a direct replacement option for buyers looking for a charging system match by fitment and output.

Key Features

• 210 amp output for higher electrical demand
• 100% new construction, not remanufactured
• Internal fan and internal regulator design
• Clockwise rotation with a 6-groove serpentine pulley
• Decoupled clutch pulley included
• Denso family application match

Product Details

Part number 14204N is designed for BMW charging system applications that specify a Denso IR/IF alternator with 210 amp output. Its internal fan, internal regulator, and serpentine pulley setup support a factory-style electrical replacement for vehicles such as the BMW 320i, BMW 328i, and BMW X3. The 14204N also cross-references Carlson 14204 for the same application.

Because this unit is built new with proprietary components and processes, it is suited for replacing a worn or underperforming alternator when the original charging system no longer maintains proper output. The 14204N helps restore stable charging performance in BMW 528i, BMW X4, and other listed fitments.

Common Uses

• Low charging output or battery warning lights
• Electrical system voltage drop under load
• Alternator noise from worn internal components
• Charging failure caused by pulley or regulator wear
• Replacement for a failed Denso-style 210 amp unit

Installation Notes

Verify the vehicle’s alternator family, amperage rating, pulley style, and rotation direction before installation. This unit uses a clockwise rotation, internal regulator, and 6-groove serpentine pulley configuration. Confirm fitment against the listed BMW applications and Denso IR/IF notes before ordering.

Quality Assurance

WAI states that this alternator is 100% new and manufactured with proprietary components and processes to support long service life and consistent performance.
