I don't think you can purchase that cap. I believe each engine has the cap machined to it's own individual spec. You would need to get the cap machined if you got a hold of one.

I remember looking for a cap to replace one of mine and couldn't find it being listed anywhere on the Acura parts list.

If you need to replace it, your best bet would be to find a replacement head and swap out what u need.....after getting it machined to your heads' spec of course.
