Show original supplier description

The IHI IS20 turbocharger, part number 06K145874M, is a complete assembly featuring the turbo and an integrated diverter valve. This RHF5-series turbo is designed for Gen 3 2.0T and 1.8T engines, serving as a direct replacement for various Audi and Volkswagen models including the A3, TT, Alltrack, Arteon, Atlas, Golf VII, and Jetta VII GLI. This specific IS20 model is the latest iteration, often found on the 2022+ Jetta GLI. A key feature is the PCV port located near the turbo outlet, which enables compatibility with the newer PCV valve systems found on the MK8 GTI or Golf R. For those looking to perform this OEM+ upgrade, a separate retrofit kit is available. If the PCV upgrade is not desired, IHI includes a plug in the box to seal the additional port. The product is backed by a Lifetime Replacement Program, offering coverage for as long as the original purchaser owns the product. Note that while the product fits numerous Audi and Volkswagen applications with 1.8T and 2.0T Gen3 engines, it is always recommended to use the vehicle selector tool to confirm exact fitment for your specific vehicle.
