Denso Alternators
A popular choice among enthusiasts, the Nippondenso, or
often called Denso, style alternator is the “better” choice when it comes to
alternators in Turbo Dodge vehicles. The
Denso style alternator is regarded as more reliable and easier to rebuild
compared to the Bosch style alternator.
Introduced in the 1989 model year, this alternator can be used in many
80s and 90s Turbo Dodge vehicles. Some
modification is required on 1989 and prior L-body vehicles for installation.
Advantages & Disadvantages
One of the main advantages to the Denso style alternator is
the fact it is offered in a 120 amp form.
Other advantages include its smaller size, light weight, and its ease of
rebuilding. However, Denso style
alternators tend to be slightly more expensive than their Bosch counterpart.

Identification
The Bosch style alternator is identified by its external
fan. The Denso alternator does not have
an external fan. The confusion in
identifying these alternators is by rebuild companies who attach their brand
name to the style of alternator. For
example, Bosch will rebuild a Denso style
alternator, and market under their name brand.
Just remember, that Denso style alternators do not have an external fan.

Conclusion
If you are trying to decide between a Bosch and Denso
starter based on reliability or perhaps space savings, the Denso style
alternator is a great choice.
Furthermore, if you have high power devices in your car that tend to dim
your lights, the 120 amp Denso is a great choice. There is really nothing bad with the Bosch
alternator, however, the Denso style should be your first choice.
