ARD Advance High-Power 150A Alternator (Red) for Mazda RX8 (Series 1 & 2, 2003-2012)

Upgrade the charging system with a high-output alternator in a bold finish that supports heavy electrical loads and keeps voltage stable under all conditions.

$780

This ARD Advance High-Power 150A Alternator (Red) offers the same proven performance as the blue variant for Mazda RX8 Series 1 & Series 2 models (2003–2012), combining OEM-supplier quality with upgraded internals to deliver a stronger, more reliable and efficient charging system for modified or accessory-heavy cars.

Upgrades the alternator to a 150A high-output unit, compared to the factory unit’s lower output
Improves engine response and drivability by maintaining a more stable voltage under varying loads
Supports a stronger, cleaner ignition spark for more efficient fuel burn
Reduces electrical noise and dimming in lighting and audio systems during heavy demand
Designed with a low-resistance architecture for enhanced efficiency and longevity

You will experience more consistent electrical performance and reduced strain on the charging system, especially beneficial for RX8s (2003–2012) with upgraded ignition, lighting or sound systems.

If you prefer a blue housing to match your engine bay theme, choose the ARD Advance High-Power 150A Alternator (Blue), and pair either alternator with the ARD Advanced Power Starter Motor for a robust electrical upgrade package.
