I know everyone knows this but it's worth adding,,, so if you do anything to the motor or the ECU / PCM you're done,, no more warranty. - FYI - this car has a BLACK BOX //// event recorder so don't think you can change something and then change it back before you go in for maint. - they will know. Also you will have a tuff time finding aftermarket performance stuff for this vehicle / application. The reasons are the following: It's a newer design so you have to allow time for people to figure it out and start building up the add ons. Also KIA is well known for sweeping quick design changes, in other words these guys put blood sweat and tears into figuring some of this stuff out only to be thrown a trump card within maybe even one model year. 1 to 1 custom application are mainly being done in Korea, simply because they got a head start on all of us. Again the applications are 1 to 1 and completely custom, so you will pay out the wazu for this stuff as it's not mass manufactured / wholesaled / retailed yet. Once you receive your shipment most likely from Korea,,,, you will need someone here that really know there stuff under the hood, and someone I suggest that their daily job is working on Korean cars //// Kia / Hyundai. Depending on what you do you'll need to have the ECU flashed with new tuning, and you may even have to go as far as adding a secondary or replacing it,,,, which gets you into a whole other arena as far as $$$$$. You have to weigh it out. If your car is a daily driver my suggestion don't mess with the motor. If you enjoy projects and have the $$$ to play go for it. After you finish there are a ton of HTS parts both front and rear you can CNC from Aluminum / Carbon and swap to help get the weight down. This car with a little weight off, a little more giddy and a tighter torque curve with better shift points ( higher RPMS ), is a BEAST. It's fun but an expensive and time consuming hobby. I have 3 / 4 months involved in mine, and several thousands of dollars.
