Product Details
10X Entries For Our Spin To Win Sweepstakes!
Due to its weak plastic construction, the factory plastic PCV breather hose is known to fail. After years of consistent exposure to high engine bay temperatures and chemical-laden oil vapors, the corrugated rubber tubing can crack, crumble, or fail altogether.
Upgrade your MK5/MK6 TSI PCV system with our durable silicone breather hose, designed to provide a comprehensive upgrade and permanent replacement for the factory plastic hose. By replacing the flimsy, heat-hardened OEM plastic hose with our four-ply fluorosilicone hose, you'll experience peace of mind knowing your TSI is free from the inevitable return of oil leaks and drivability concerns that would have been.
This breather hose is found at the front of the engine and is used to connect the PCV to the intake manifold. It replaces OE part number 06J103221A.
FEATURES
- Silicone construction ensures a durable replacement that is sure to outlast OE plastic
- Aluminum fittings provide increased resilience over OE plastic and are black anodized for long-term corrosion resistance
- Dual Viton o-rings yield greater sealing power than stock, guaranteeing a perfect, leak-free seal
- Works seamlessly with the OEM manifold and air-oil-separator (AOS), as well as the ECS 2.0T Boost Tap (ES#2718328)
DESIGN
- Four-ply fluorosilicone hose construction
- Black anodized 6061-T6 billet aluminum fittings feature precision-cut o-ring grooves
- Viton o-rings are pre-installed in billet aluminum connectors
- Includes corrosion-resistant 430 stainless steel hose clamps
