Not sure who makes them but they are much better than stock springs. My ACS looked like stock springs. Black. You shouldn't have any issues with warranty. I had mine installed at the dealer and it doesn't void warranty. Even if you install them at a good shop you should be fine. I asked my service manager and that's what he said.
