Starter for Mazda and Toyota applications

This WAI starter, part number 16377N, is built for select Mazda, Toyota, and Scion applications that require a permanent magnet gear reduction design. It is a 100% new unit, not remanufactured, and is engineered to deliver the amp output needed for modern electrical demands.

Key features

• Permanent magnet gear reduction design for efficient cranking performance.
• 100% new construction, not remanufactured.
• 11-tooth drive configuration for listed applications.
• Clockwise rotation with flange mounting.
• 1.4 kW power rating for supported starting systems.

Detailed description

Part number 16377N is a WAI starter built around a Mitsubishi family design and specified for a range of Mazda 3, Mazda CX-3, Mazda CX-5, Toyota Yaris, Toyota Yaris iA, and Scion iA applications. Fitment includes 2012-2022 Mazda 3, 2014-2021 Mazda CX-3, 2014-2016 Mazda CX-5, 2019-2020 Toyota Yaris, 2017-2018 Toyota Yaris iA, and 2016 Scion iA, with notes for certain Japan-built and Mexico-built vehicles. The permanent magnet gear reduction layout supports strong starting performance in compact packaging, while the 11-tooth, clockwise-rotation, flange-mount configuration matches the listed applications. This part cross-references Walker Exhaust 16377 for the same application.

What this starter helps address

• Slow or weak engine cranking.
• No-start conditions caused by starter failure.
• Intermittent starter engagement.
• Electrical load demands on modern starting systems.
• Fitment issues when the original starter uses the same Mitsubishi PMGR 11-tooth setup.

Installation notes and quality assurance

Verify the vehicle year, build origin, and starter configuration before installation, especially on Mazda 3 and Mazda CX-5 applications with build-specific notes. Confirm clockwise rotation, 11-tooth drive count, and flange mounting against the original unit before replacement. WAI states that this starter is engineered to provide the amp output required by today’s vehicles and is manufactured as a new unit using proprietary components and processes for service life and performance.
