Product Number: 21881N
Find the right Starter Motor & Alternator for your Machine
Starter Motor & Alternator FinderThe WAI 21881N is a brand-new 12V 50A alternator. It is built to replace DENSO original-equipment units — specifically DENSO 100211-6660 and DENSO 100211-6730 — in Daihatsu applications. With an IR/IF (internal regulator / internal fan) design and clockwise rotation, it is engineered to the same functional specification as the DENSO units it replaces, making it a direct-fit replacement rather than a compromise substitute.
The alternator carries a V1 single-groove pulley and is referenced under Lester number 21881, which allows straightforward cross-referencing against catalogues and workshop databases. The IR/IF architecture keeps all regulation circuitry self-contained within the unit, simplifying installation and eliminating the need for an external voltage regulator.
Fitment covers four Daihatsu applications, including the FEROZA Soft Top (F300) with the HDC 1.6 16V 63 kW engine (1989–1991), the HIJET Box (S85) with the HCE 1.3i 16V 48 kW engine (1998–2004), the HIJET Pickup with the HCE 1.3 48 kW engine (1998–2004), and the Sportrak (1989–1998). Use the selection widget or search by OEM number to confirm fit for your exact vehicle and engine variant.
