TGK-0311-02
The factory PCV breather system on EA839 engines represents a critical failure point under turbocharged conditions. OEM plastic quick-connects, thin hose construction, and fragile diaphragm check valves are inadequate for high-boost crankcase pressures—particularly on tuned applications where system reliability is non-negotiable. The TGK Motorsport PCV Breather Line Kit completely eliminates these vulnerabilities with precision-engineered components designed for sustained high-performance operation.
This system was engineered from the ground up to address every weakness in the OEM design through superior materials science and valve architecture. Available with either TGK Premium Billet Aluminum fittings for maximum durability or TGK OE Style Plastic fittings for cost-effective reliability, both configurations deliver significantly enhanced pressure handling and long-term service life. This is not a band-aid solution—it's a permanent upgrade that supports everything from stock daily drivers to aggressive Stage 2+ builds without compromise.

✓
Precision Piston-Style Check ValvesMachined piston design provides instantaneous sealing under boost with consistent operation regardless of heat cycling or oil vapor contamination, validated beyond 40 PSI continuous operation.
✓
Premium Construction OptionsChoose between CNC-machined 6061-T6 billet aluminum for ultimate durability or high-grade engineering plastic for enhanced reliability over OEM at reduced cost.
✓
FKM-Lined Multi-Ply Silicone HoseReinforced silicone construction with inner FKM fluoroelastomer liner prevents oil vapor saturation and external seepage while maintaining structural integrity under extreme conditions.
✓
OE-Correct IntegrationDirect replacement design maintains factory air-oil separator routing and engine cover fitment while preserving both OEM vacuum reference points without modifications or adapters.
✓
Intelligent Pressure ManagementAt idle and light load, crankcase vapors evacuate through post-throttle vacuum; under boost conditions, piston valve immediately seals and redirects flow to turbo inlet vacuum source.
✓
High-Performance ValidatedEngineered as a permanent solution for stock through Stage 2+ applications without degradation—eliminates the OEM system as a consumable failure point across all power levels.
