Hi everyone, my friend just bought an 2017 IS350 F-Sport. He wants to put a cold air intake on it. However, they stopped making them after 2014. And the older one's don't fit. The question is, if any, what kind of cold air intake would be acceptable without voiding the warranty? I'm asking here because the dealership said they said there were none. Although a great dealership, I figured getting a second opinion would help because it didn't seem like something they get asked a lot.
