The SM 8470 is a precision-engineered Alternator Rectifier Assembly designed specifically for the Toyota Qualis (FS / GS / RS models). This unit utilizes a specialized DEN.TYPE (Denso Type) architecture, which is a direct replacement for the high-durability, compact alternators found in Toyota’s 2.4L Diesel and 2.0L Petrol engines. It is engineered to provide the high-amperage, stable DC output required for the Qualis’s robust electrical system and dual-unit air conditioning.
