How does this alternator match my Honda’s original equipment?

The 11573 is manufactured to OEM-compatible dimensions and tested against common performance criteria so it installs like the factory unit. It uses an internal voltage regulator and internal fan, and the mounting position and pulley configuration mirror the original for the specified model years.

• Electrical specs: 12V, 130A output for modern accessory loads.
• Rotation: CW (clockwise) to match factory orientation.
• Pulley: 6-groove pulley for accessory belt compatibility.
• Mounting position: 11:00 o’clock alignment for direct replacement.

What performance and durability features does the HAYIAUTO 11573 include?

HAYIAUTO builds the 11573 with CNC-machined castings and high-grade aluminum to control weight and improve heat dissipation. Critical components like bearings are tested to OEM tolerances and the rotor/stator receive insulating treatments to reduce shorts and extend life under load.

• Precision CNC castings for reduced vibration and noise.
• OEM-grade bearing testing and lubrication for longevity.
• Sealed rotor/stator coatings to protect against electrical faults.
• Accelerated cycle and heat-resistance testing before shipment.
