The Bosch AL3370X is a 110-amp, 12-volt remanufactured-style replacement alternator with an internal fan and aluminum housing. It is a direct-fit unit for a range of Toyota cars, so it suits owners replacing a tired or failed factory alternator rather than anyone building a custom charging system. At 110 amps it has enough headroom for a standard car electrical load, but it is not a high-output unit for heavy audio or winch setups. Bosch's remanufactured alternators are widely regarded as a solid middle ground between cheap no-name units and new OEM parts.
