Has anyone used aluminum valve covers 13264-AM600-10 from CZP, aka conceptzperformance (www.conceptzperformance.com)?

If so, do you have an opinion (review) about them that you would like to share?

My purpose in asking is finding a valve cover that corrects for leaking spark plug tubes for my 2000 G35. While fixing its leaking valve cover gaskets, I learned that my OEM covers each had one tube where oil had invaded. I have wasted far too much time searching for replacement covers that correct that issue. These might do that, I think, but I need confirmation.

 

Yes they will work. We just recommend Oem gaskets rather than that magic the Amazon / CZP ones typically come with

 

@Urbanengineer I thank you for responding quickly, as I would certainly like to make some selection asap.

When you recommend OEM gaskets over those provided by CZP, I assume you are talking about the valve cover gasket that seals the cover to the head. I know any third party supplier would buy the cheapest thing they could find to make selling price as low as possible, to be competitive, so that makes sense to me. Is there a "favorite" cover gasket the community recognizes, or do they look for an OEM?

When saying "Yes, they will work," are you saying that you believe the CZP cover fixes the much discussed spark plug tube seal problem? The CZP covers have replaceable tube seals, so if they leak they can be fixed by replacing the seals, but the better question is do they seal against the oil leak on first install?
