If you're an Audi A4 1.8T Turbo owner from 2002, you've probably felt the limitations of the factory turbo inlet hose. As your turbo spins up and builds boost, the vacuum pressure before the turbo increases, causing the flexible rubber inlet hose to collapse under pressure. This results in a choked turbo, slower spool times, and less responsive throttle. It's a frustrating bottleneck that can hold back your performance upgrades, especially if you’ve cranked up the boost with chip or turbo upgrades.
Enter the Evolution Racewerks AU-INT002P Turbo Inlet Pipe (TIP). This meticulously engineered upgrade is designed to eliminate the issues caused by that factory rubber hose. Constructed from high-grade 6061 aluminum, this inlet pipe maintains a consistent diameter regardless of vacuum pressures, ensuring your turbo gets the airflow it craves, especially at peak boost levels.
With the AU-INT002P installed, you can expect faster turbo spool times and enhanced throttle response. This means your A4 will feel more alive, especially when you’re pushing it hard. Whether you're hitting the track or just enjoying a spirited drive, this upgrade will help you tap into your vehicle's full potential.
Audi A4 owners have reported noticeable improvements in performance after installing the AU-INT002P. One owner remarked, "After switching to the Evolution Racewerks inlet pipe, my turbo spools up quicker, and I can feel the difference in throttle response. It's a must-have for anyone pushing their A4!"
Don't let a collapsing factory inlet hose hold back your Audi A4's performance. Upgrade to the Evolution Racewerks AU-INT002P and experience the difference for yourself!
