I believe those are the new Nissan gaskets - more like a mixture of cardboard and staples.

Tell them to refund your money and get the EPS kit if you can :twocents:

Meh, not really, I'm in Slovenia and it seems they don't ship there.
Are the renewed gaskets that bad? I mean, I believe they are factory installed on newer models which have no gasket issues, so I guess they should be good enough, right?

The newer gaskets are probably fine. It's not just the gasket material but also the hardware they used that can cause problems - the EPS kit includes new hardware too. The Nissan bolts tend to back out on their own over time which allows oil to pass by the gaskets and eventually they may blow out.

If you have to go with the Nissan kit, just make sure they stake the bolts when installing the new gaskets.
