The Evolution Racewerks Turbo Inlet Pipe (TIP) is engineered specifically for the Audi A4 B5 1.8T models produced between 1996 and 2001, featuring the OEM MAF. This component addresses critical airflow issues that arise with factory turbo inlet hoses, particularly when subjected to increased boost pressures from performance upgrades.
Constructed from high-grade 6061 aluminum, the AU-INT001P offers a robust yet lightweight solution to the common pitfalls of the stock inlet hose. The piping maintains a consistent diameter under varying vacuum pressures, effectively eliminating the risk of collapse that can choke the turbo, especially at peak boost levels.
With the Evolution Racewerks Turbo Inlet Pipe, you can expect enhanced airflow to the turbo, resulting in quicker spool times and improved throttle response. This upgrade is particularly beneficial for those running increased boost levels, ensuring that your turbo operates efficiently without the risk of suffocation that can occur with the factory setup.
