The Killer B Alternator Cover for your Subaru WRX / STI is a simple method of increasing the efficiency of the factory radiator up to 15%. A side benefit is a cleaner engine compartment. Our Radiator Shrouds are made from aircraft grade Aluminum and are available in Black Powder Coat. Unlike other manufacturer’s choice of materials, our aluminum piece WILL transfer heat from your radiator, especially in stop and go driving. The intent with this piece was to make a Radiator Shroud that was light, inexpensive, good looking, and competitively priced. 06-07 version may fit Saabaru.

The Alternator Shroud is made from .09” thick sheet aluminum, formed to use the factory mounting locations, matches the Killer B Motorsport Radiator Shroud and Washer Reservoir perfectly, provides protection from the pulleys and belts, has stainless hardware, and lastly the quality you’ve come to expect from our products.
