300 SERIES ALTERNATORS
The WOSP ‘300 Series’ utilise the latest generation brand new OE Denso based segment
conductor design of alternator tailored to be plug & play. Almost the entire 300 series range
(which is currently over 1200 part numbers) have a full CNC billet case in order to be direct
replacements to the original alternator which would currently be fitted to your vehicle.
Similar to the WOSP starters which can be built using different platforms depending on desired
size & output, these alternators fall in to four main categories which are explained in the tables
below. Whatever your requirements WOSP are sure to have a high quality and durable solution.
Are you driven by output or size or both? Call for more details on the correct part for your vehicle.

*HO units often need 1.5-2 x higher speed for output and cooling.
This makes them less efficient than a STD unit at low rpm.
