The TTE420 is a high-performance hybrid turbo based on a new BorgWarner K04-064, specially developed for the VAG 2.0 TFSI EA113 engines. This upgrade delivers a significant power boost whilst retaining Plug & Play installation and a fast, predictable response. Thanks to clever engineering, the TTE420 combines the character of the original K04 with considerably greater airflow, power and reliability.
