This new Sinister Diesel Oil Fill Cap functions like a factory cap, but features custom Sinister Diesel looks. The cap fits 1999-2010 Powerstroke engines and 2007.5-2019 Dodge/Ram Cummins engines. It is made from CNC machined, solid billet T6-6061 aluminum Available in gray or Sinister Blue, this cap looks as good as it works!
