Hundred Proof Oil Cap

  • Introducing another original design from MPC – our Hundred Proof Oil Cap.


    Designed to flow seamlessly with the rest of our product line, this Oil Cap features a custom machined allen head bolt which can be used to lock down or remove the oil cap from your valve cover! This fastener is locked in place, so you never have to worry about it backing out.


    MPC oil caps utilize a high-heat Viton O-Ring for years of worry-free use.
