Delco Remy 28SI high output Alternators are designed to address vehicle applications that require higher electrical output, but also want lower weight, improved temperature capability, and fuel savings.  Vehicles, such as school buses, not using a premium high output alternator will likely experience premature failures due to high under-hood engine temperatures.  Delco Remy 28SI alternators are designed using our Dual Internal Fan technology which improves the operating efficiency and durability of the unit.

1. 28SI Alternators can withstand high under-hood engine temperatures of up to 125°C
2. 28SI Alternators come standard with Remote Sense technology
3. 28SI Alternators provide higher electrical output up to 200Amps
