Description
The 034Motorsport Catch Can Kit for the Audi S4, S5, RS4 and RS5 (EA839 engine) Replaces the weak original PCV hose with a high-quality, pressure-resistant system that traps oil deposits before they reach the intake. This upgrade prevents boost leaks, increases reliability, and extends the life of your engine.
The system includes a baffled billet aluminum catch can, which filters oil and water vapor from the crankcase ventilation, so that only clean air is returned to the intake. The renewed breathing hose of 22.5 mm diameter guarantees optimum flow and prevents overpressure in the crankcase, even at boost levels above 40 PSI.
The 034Motorsport Catch Can is designed for a perfect fit, retention of the original engine cover and easy maintenance thanks to the integrated dipstick and drain.
