These came in a Fel-Pro head gasket set. The big round gasket is to the throttle body. The four white ones are made of a hard plastic. Thanks

 

My guess for the four white ones is intake manifold gaskets, but they gotta be flexible enough to take the shape of a bent oval.

 

The white ones are fairly hard plastic and are the updated intake cam "rectangring" made of teflon, part# 11317587757 . These replace the metal ones. The metal gasket is for the N12 motor. Still not sure about the other two smaller o-rings.

 

If I knew which engine the set was for, I wouldn't have responded. My '07 N14 intake cam only has 2 rectangrings, and none on the exhaust cam. Also, my head gasket kits don't include either your metal gasket or a throttle body gasket, it has only N14 stuff that's used for the head. But, I don't use Felpro either, at least not yet.

If you don't find these gaskets during disassembly, you shouldn't need to worry about them --- just replace the gaskets you find. Depending on what you're tearing down, there's bound to be extra gaskets in the kit.

 

This set is for a N14 and came with an exhaust gasket instead of the head gasket. It is strange how it includes n12 stuff. The extra 2 rectarings are for the n12 exhaust cam. I'm kind of OCD about using everything is a set especially when the set costs $121 shipped. I'm always thinking, did I miss something somewhere?

Which set do you use? My ideal set would have the vacuum pump o-ring, HPFP o-ring, and fuel injector bits that this set did not.

 

I've been using the dealer's set --- same one as listed in RealOEM, has everything except head and exhaust gaskets, nothing extra. Now that their price has gone up to over $300, I'm gonna shop around our various vendors.
