WAI 19071N Starter

Starter for Subaru Applications

This WAI starter, part number 19071N, is built for Subaru WRX STI and Subaru Impreza applications that require a flange-mounted, counterclockwise rotating starter with a 9-tooth drive. It is a direct-fit electrical replacement for the listed vehicles and uses a planetary gear reduction design for efficient cranking performance.

Key Features

• 100% new starter construction, not remanufactured.
• Planetary gear reduction design for compact, efficient operation.
• Counterclockwise rotation with 9-tooth engagement.
• Flange mounting type for the specified applications.
• Built with DENSO family architecture.

Detailed Description

The WAI 19071N starter is engineered to deliver the amp output needed by modern electrical systems while maintaining consistent starting performance. Its 12-volt design, 0.9 power rating, and DENSO family construction make it a fitment-specific replacement for Subaru WRX STI and Subaru Impreza models listed below. If you are replacing a worn starter on a Subaru WRX STI or Subaru Impreza, this unit matches the required rotation, tooth count, and mounting style for the application.

This part cross-references BBB Industries 19071 for the same application.

What It Helps Solve

• Slow or weak engine cranking.
• No-start conditions caused by starter failure.
• Intermittent starting due to worn internal components.
• Incorrect rotation or tooth engagement from the wrong starter.
