Hello, you are looking at a brand new Novarossi OEM original .21 red gaskets for engines that have the shaped outlet on the case. This is Novarossi part #21000/2 and this is only for engine cases that have a shaped exhaust port on the case, (not the standard lip). This fits the newer style Novarossi exhaust cases such as the mephisto, bonito, mito, etc. These only fit Novarossi engines and if your engine came with a red gasket, this is the one you need. If it came with a blue or black gasket, this is the wrong one.
This is out of the package but 100% original novarossi out of the factory.
If you have any questions, please ask before bidding.
Thanks for looking and good luck!
