Product Description

IROZ Motorsport Stage 3 Engine Catch Can Kit

Fitment: All Audi RS3 (8V) & TTRS (8S) DAZA Engines 

Extreme horsepower applications commonly suffer from excessive crankcase pressure. Correcting this results in better engine efficiency and free horsepower your engine has been holding back.

While the OEM PCV system on the DAZA Based 2.5TFSI does an incredible job at separating oil from the crankcase gases, it starts to be easily overpowered as we increase the boost and horsepower. As we instrumented on 2019+ cars, we realized that those cars were significantly worse than the earlier 2017-2018 cars. The bulk of this issue was that they use boost to drive a siphon jet that evacuates crankcase better at lower boost levels.  The issue with this design is that it is very undersized for anything over factory power levels.

Extreme boost pressures can result in high crankcase pressures. This can result in loss of power and engine efficiency under boost. Oil Leaks are common as well as crankcase pressure pushing oil past seals. We originally decided to come up with a kit to convert 2019+ 2.5TFSI engines to 2017-2018 spec which featured a much larger diameter PCV setup for superior crankcase evacuation. We also wanted to solve the inherent issues with the plastic that warps and creates vac / boost leaks on 2017-2020 and a new a metal version would correct that.

The factory crankcase ventilation system is a positive crankcase ventilated design. When under Extreme boost levels this translates to excessive pressures reaching as high as 6+psi.

We have approached a solution for this that retains the factory oil separation plate while allowing for full pressure evacuation. All 3 stages will retrofit 2019+ cars to 2017-18 style PCV systems, with a provided cap to delete the boost jet for 2019+ cars.
