This new Coolant Reservoir (Degas) Cap functions like a factory cap but features custom Sinister Diesel looks and upgraded quality since 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. Finished in Sinister Blue, this cap looks as good as it works!
