New to the forum, just picked up my 2019 Stinger GT1 ceramic silver two weeks ago. I've watched a lot of videos on these cars and found out that the first two things you need to get, are HKS M45iL Spark Plugs and a OCC oil catch can and a PCV oil catch can. Biggest benefit to running the OCC’s… reduction of carbon build up on the back of the intake valves. If you Google search GDI and carbon build up, you will see how much carbon build up happens with GDI applications with the PCV systems. I also heard changing out the rear sway bar makes a huge difference on the handling of the car. FYI for all the owners out there, kia told me that they have been getting some of these cars back with blown motors an the reason why the owners have been over revving the engine and blown the left side turbo up so be careful. See you all out an about. Drive safe
