IAG Alternator Cover - 2006-14 Subaru WRX & 2004-21 STI

The IAG Alternator Cover replaces the dull factory plastic with a sleek aluminum design, adding a custom touch to your Subaru’s engine bay. Designed as a direct replacement for 2006-2014 WRX and 2004-2021 STI Subaru models, this aluminum cover is available in black with your choice of a red, neon yellow, black, white, blue, or pink hexagon accent plate. It’s a simple way to give your Subaru’s engine bay a fresh, stylish touch.

The IAG Alternator Cover is precision laser-cut and formed from lightweight yet durable 5052 aluminum at our Westminster, Maryland facility. Stronger than the OEM plastic, this cover is built to last. It features our signature hexagon pattern, along with a laser-etched IAG logo, giving it a refined, modern appearance, while the powder-coated finish ensures long-term protection against corrosion.

Installing the IAG Alternator Cover is quick and hassle-free—no cutting, drilling, or modifications required. It mounts directly to your Subaru’s factory mounting points and includes all necessary hardware. With just basic hand tools, you can have it installed in under 10 minutes.
