What are the technical specs and why do they matter?

The ILONPA alternator delivers 12 volts at 130 amps with internal regulation and a CW rotation—specs chosen to replicate the original equipment. Matching these parameters ensures correct electrical output, pulley alignment, and long-term reliability under typical engine bay conditions.

• Voltage: 12V — standard automotive charging system output
• Amperage: 130A — sufficient for stock electrical loads and accessories
• Rotation: Clockwise (CW) — matches factory orientation for affected engines
• Pulley: SD7 class with IF fan, and integrated IR regulator

How does installation and quality assurance work?

Designed as a direct replacement, this alternator mounts where the original unit did and connects to the same harness and belt routing when matched to the correct model and part number. ILONPA tests each unit for electrical output and durability to give you a consistent replacement that meets factory-like specifications.

• Factory-spec manufacturing for fit and function
• Bench-tested for performance and heat endurance
• Direct electrical connectors and mounting points for compatible models
• One-year warranty with customer support for post-purchase issues

Will this alternator handle extra electronics or towing loads?

At 130 amps, the unit supports standard factory accessories and many common aftermarket add-ons, but extreme electrical upgrades or heavy towing with extensive auxiliary systems may demand a higher-capacity alternator. Always review total system draw before assuming surplus capacity.

• Good for stock setups and moderate accessory loads
• Not intended as an upgrade for high-output audio or extreme lighting arrays
• Check cumulative amp draw of added devices to confirm adequacy
