V6 ASTOU Alternator Compatible with Honda and Acura - High Output 130A

In this review the ASTOU V6 alternator is assessed for owners needing a direct replacement for specific Honda and Acura V6 engines. It is aimed at DIY mechanics and independent shops who want a high output, 130A, 12V unit that matches OEM fit numbers like Lester 11391 and Honda 31100-RGW-A01RM. The bottom line: this alternator offers a solid, direct-replacement build with die-cast aluminum covers and continuous stator output, making it a sensible choice when the original unit fails and a like-for-like spec is required.

Key Features

• Direct replacement fit: Matches OEM reference numbers such as Lester 11391 and Honda 31100-RGW-A01RM so it installs without major modification for the listed models.
• High output charging: Rated at 130Amp and 12V to provide stronger charging capacity for vehicles with standard electrical loads and accessories.
• Durable construction: Aluminum alloy die-cast front and rear covers improve structural durability compared with lower quality housings.
• Stable generation: Continuous stator design and improved carbon brushes deliver consistent starting force and steady charging performance.
• OEM-style pulley and regulator: Comes with a 6-groove pulley, internal regulator (IR), and CW rotation to match factory pulley and belt configurations.
• Broad vehicle coverage: Specified for multiple Honda Odyssey, Pilot, Ridgeline and several Acura V6 applications, simplifying sourcing for those platforms.

Who It's For

This alternator is best for owners of 2008-2011 Honda Odyssey, 2009-2011 Pilot and Ridgeline models and for many Acura V6 models listed, who need a like-for-like replacement with 130A output. It suits DIY installers and independent shops that want an alternator built to OEM matching numbers and the convenience of a direct swap.

Those who should look elsewhere include drivers with extensive aftermarket electrical systems that may require higher than 130A output, or owners of unrelated vehicle models not listed in the fitment. Also, if long-term durability beyond typical aftermarket expectations is a priority, sourcing from a documented OEM supplier or a unit with longer proven field life may be preferable.
