This cover is made from Type 304 polished stainless and attaches to two of the existing bolts on your stock alternator. It is designed to compliment the intake cover and the belt tensioner cover also available from us. It is vented so heat will not build on your alternator. Because of its design no part of this cover comes in contact with your electrical connectors. Comes with easy to follow directions. Polished stainless is very easy to maintain and keep clean.
