Alternator Fits Honda Odyssey Pilot Acura MDX 3.5L - 130Amp CW

In this review of the SCITOO alternator fitment for Honda Odyssey, Honda Pilot and Acura MDX 3.5L engines, the bottom line is practical: this is a cost-conscious, direct OE replacement for drivers who need reliable charging capacity without dealer pricing. The review focuses on fit, electrical output and ease of installation; the single biggest reason to buy is the alternator's direct OEM compatibility with part numbers like 31100-PGK-A01/A02 and its 130Amp, 12V output that matches factory requirements for these V6 models.

Key Features

• Direct fitment: Built to replace OE numbers 13918 and 31100-PGK-A01/A02 so installation fits factory mounting points without modification.
• 130Amp output: Provides the higher charging capacity modern accessories demand, helping maintain battery charge under load.
• 12V, CW rotation: Matches the original electrical and mechanical rotation orientation for the listed 3.5L V6 engines to ensure correct operation.
• Internal regulator and fan: Includes an IR regulator and IF fan which simplifies wiring and preserves cooling similar to OEM units.
• 6-groove pulley: Equipped with the correct pulley profile to fit factory belt systems and reduce belt slippage risks.
• New, tested bearings: CNC machined castings and tested bearings aim to meet OE durability expectations out of the box.

Who It's For

This alternator is aimed at owners of 2001-2002 Acura MDX and 2002-2004 Honda Odyssey or 2003-2004 Honda Pilot with the 3.5L V6 who need a direct replacement alternator that matches factory electrical specs. It is especially suited to DIYers and independent shops that want a part which bolts in, uses the factory belt and electrical connections, and restores charging capacity quickly.

Buyers who expect extended heavy-duty life under extreme conditions or who need manufacturer warranty support for a new vehicle may want to consider dealer remanufactured units; some customers report mixed long-term durability compared with OE remanufactured alternators.
