Detailed Description

WAI designs starters to deliver the amperage output needed for modern vehicle electrical demands. The 16366N starter uses proprietary components and manufacturing processes to support consistent operation and long service life. Its DENSO family design, 12-volt electrical specification, and permanent magnet gear reduction layout make it a fitment-focused replacement for select Toyota starting systems.

For Toyota Highlander and Toyota Sienna models, this starter matches the listed rotation, tooth count, and mounting configuration required by the application. If you are replacing a worn starter on a 2017-2022 Toyota Highlander or a 2017-2020 Toyota Sienna, the 16366N provides the correct electrical and mechanical setup for those vehicles. This part number, 16366N, is also cross-referenced with Dixie Electric Ltd 16366 and OE numbers 28100-0P110 and 438000-3390 for the same application.
