This is our New bolt on option for the 2016+ Kia optima/Hyundai sonata TD04L turbos. The compressor housings are sonic tested for thickness to ensure you are getting the most out of your turbo upgrade. This allows us to find the material thickness of the compressor housing to see exactly how much material can be removed to fit a larger compressor wheel while also taking shaft strength into account. (a core is required but can be exchanged after installation. Core charge is $600.)
