034Motorsport PCV Breather Hose Upgrade - Audi B9 S4/S5/SQ5 3.0TFSI - 034-101-3108
This PCV breather hose replaces the factory corrugated plastic hose on the EA839 3.0 TFSI V6 in the Audi B9 S4, S5 and SQ5. 034Motorsport says the factory hose relies on a pair of internal check valves that are prone to premature failure, which can let the crankcase pressurise and push hot oil out of the engine. Its replacement is designed to give reliable crankcase ventilation at all power levels, on stock cars and on Stage 1, 2 or 3 tunes alike. The brand describes it as a safety upgrade for all EA839 vehicles, not only tuned ones.
