I'm attempting to pull the plug on it now because I talked to the dealer and they said, intake/exhaust and BOV would be ok under the warranty(but no oil catch can which is weird). I daily the car 60mi 5 days a week and bought it with 23k on the dash (at 30k) so warranty if possible is great. I'm looking into an exhaust, currently have the K&N intake with the heat shield and it sounds great, but would like more. GFB adjustable bov would be perfect or even the Deceptor Pro II T9511 Diverter but GFB support said:
"-Unfortunately, for the non-GT variants for the Hyundai Sport, the T9511 Deceptor Pro II is not listed as compatible. Even through the GT and non-GT variants ha[v]e the same flange, this is due to a fitment issue that is to be encountered when attempting to install the T9511 onto your vehicle. The servo motor will clash with the surrounding piping, hoses or manifold.-"
