{"product_id":"k04-turbocharger-upgrade-2","title":"K04 Turbocharger Upgrade","description":"The CTS Turbo K04 Turbocharger Upgrade is engineered as a direct-fit replacement for the factory Borg Warner or IHI turbochargers found in B7, B8, and B8.5 Audi A4, A5, and AllRoad 2.0T vehicles. This unit utilizes a full-frame K04 CHRA housed within CTS's in-house designed compressor cover and turbine housing, avoiding the potential issues of other hybrid builds which may not offer optimal flow.\n\nConstructed with a billet compressor wheel (MFS) and heavy-duty thrust bearings, this turbocharger is VSR high-speed balanced for reliability. It is designed to be a direct replacement, requiring no additional parts for installation, though a K04-specific ECU tune is necessary. The package includes an OEM installation kit with gaskets and hardware for a smoother installation process.\n\nFitment is specific to the 2006-2009 Audi A4 2.0T, and the 2009-2015 Audi A4, A5, and AllRoad 2.0T models. Additional recommendations for optimal performance include an aftermarket high-flow catalytic converter, an aftermarket intake and intercooler system. Notably, B7 A4 models will require upgraded High-Pressure Fuel Pumps (HPFP) and fuel injectors in addition to the K04-specific tuning.\n\nPlease be aware that this turbocharger is not for sale or use in California on any pollution-controlled vehicle, as per the California Air Resources Board regulations. Trimming of the bracket on the coolant line may be required on some models.","brand":"CTS Turbo","offers":[{"title":"Default Title","offer_id":52687568929080,"sku":"TR-1070","price":1349.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664701909.webp?v=1784885172","url":"https:\/\/store.motormia.co\/products\/k04-turbocharger-upgrade-2","provider":"MOTORMIA","version":"1.0","type":"link"}
