Product Description
When you pop the hood on an STI, the first thing everyone looks at is the alternator cover. It is the centerpiece of the EJ25 engine. Unfortunately, the factory gave you a dull, grey, textured piece of plastic that looks like an afterthought. The COBB Tuning Redline Carbon Fiber Alternator Cover is the remedy. It transforms that utilitarian safety guard into a piece of under-hood art.
If you are building a clean engine bay, consistency is key. This cover uses the same 2x2 Twill Weave found on the COBB Redline Intake. When paired together, they create a cohesive, race-inspired look that flows from the front of the car to the back of the engine. The high-gloss finish catches the light perfectly, making the engine bay look wider and more aggressive.
Subaru engine bays get hot. Really hot. Cheap carbon overlays often delaminate or turn yellow over time. COBB uses a high-temp clear coat to ensure this piece stays looking crisp for the long haul. It installs effortlessly using the supplied hardware, meaning you can add a touch of class to your car in the time it takes to fill up a tank of gas.
The Redline Series is COBB's declaration that you can have race-car performance and show-car looks in the same package. The alternator cover is a small part that makes a huge visual impact. It replaces the "plastic fantastic" look with the premium feel of hand-laid carbon. Whether you are parking at a local meet or popping the hood for a tune-up, this cover ensures your STI looks the part.
