Since this is my first teardown of a Volvo (2000 S40), I'm not familiar with the two gaskets below found in my HG kit. Look spark plug related but I don't see any fitment for them on an S40? Possibly from another model that shares this HG kit?

Thanks!

 

Maybe an earlier model? My 2001 used the 4 large O-rings for the spark plug holes oil seal.
