Towards the end of last year I wanted to make an engine piece that had more aesthetics than I am normally used to.  I wanted to give it the feel and look that would show off a mechanical side of things that would also give the consumer a talking piece when they popped their hood to show off their engine bay.

What I came up with (which yes, has been done before) was my own version of the billet piston oil filler cap.  My particular oil cap fits ALL Nissan Models from the CA/SR to the RB and VR platforms.  Just to clarify all platforms it fits, here is a list.

CA18
SR20
RB (20/25/26)
VG30 (DOHC & SOHC)
VQ35 (Rev Up & HR)
VQ37
VK45/50/56
VR38

These are made of T6061 and are fully modeled after a custom CP piston we run in our assemblies.  It has an engraved company logo on top and includes an O-ring to ensure a proper seal is made.

You can get these anytime as I’ve 30 on the shelf currently.  Price is $65 shipped
