Hello I just bought a 2015 wrx 6 speed manual. I didn't notice the boost leak until a few days later when I really got on the throttle. I didn't buy a warranty. Anyways I found the boost leak buy pressurizing the intake. It was leaking at the top of the charge pipe near the intercooler. I could hear it and could feel the air passing out of that joint. When I loosened the clamp and took the charge pipe off I noticed that there was no gasket. I checked the parts diagram and there is a gasket part number 16177aa080 that is supposed to be there. I ordered the gasket. Today when I put it on it won't fit. I verified that it was the right part number. There is just not enough room. The gasket is really thick. It only goes on one way I think. I thought about buying a perrin charge pipe but that is not legal in California. What am I doing wrong?
