This new Coolant Reservoir (Degas) Cap functions like a factory cap but features custom Sinister Diesel looks. It is made from CNC machined, solid billet T6-6061 aluminum with an interior pressure relief system, so it will continue to function even in case of a gasket failure. Then for the finishing touch, it has been anodized in Sinister Blue. This cap truly looks as good as it works!
