This page gathers what we hold for the Hyundai Genesis I of 2008 to 2014 and its 2.0L Turbo G4KF engine: SUPERTECH black nitrided stainless valves, 35.00mm and 36.00mm on the inlet, 29.00mm and 30.00mm on the exhaust, and forged connecting rods.
Valves and rods are the two parts that limit a turbo Genesis once boost is raised. Replacing them takes the head and the bottom end to a level the standard components no longer hold.
Order by reference and check the dimensions on your own head.
