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.\u003c\/div\u003e\n\u003cdiv class=\"tgk-p\"\u003eThis 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.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"tgk-section\"\u003e\n\u003cdiv class=\"tgk-sh\"\u003e\n\u003cdiv class=\"tgk-ic\"\u003e\u003csvg viewbox=\"0 0 24 24\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath d=\"M3 3h18v2H3V3zm0 4h12v2H3V7zm0 4h18v2H3v-2zm0 4h12v2H3v-2zm0 4h18v2H3v-2z\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv class=\"tgk-sh-title\"\u003eSpecifications\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ctable class=\"tgk-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eEngine Compatibility\u003c\/td\u003e\n\u003ctd\u003eEA839 2.9T \/ 3.0T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction Options\u003c\/td\u003e\n\u003ctd\u003eCNC Billet Aluminum or OE Style Plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCheck Valve Design\u003c\/td\u003e\n\u003ctd\u003ePrecision Piston-Style\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHose Material\u003c\/td\u003e\n\u003ctd\u003eFKM-Lined Multi-Ply Silicone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd\u003e40+ PSI Tested\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003eDirect OE Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"tgk-section\"\u003e\n\u003cdiv class=\"tgk-sh\"\u003e\n\u003cdiv class=\"tgk-ic\"\u003e\u003csvg viewbox=\"0 0 24 24\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath d=\"M3 3h18v2H3V3zm0 4h12v2H3V7zm0 4h18v2H3v-2zm0 4h12v2H3v-2zm0 4h18v2H3v-2z\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv class=\"tgk-sh-title\"\u003eConfiguration Options\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ctable class=\"tgk-cmp\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003cth class=\"th-teal\"\u003eBillet Aluminum Kit\u003c\/th\u003e\n\u003cth class=\"th-org\"\u003eOE Style Plastic Kit\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitting Material\u003c\/td\u003e\n\u003ctd class=\"ct\"\u003eCNC-Machined 6061-T6 Aluminum\u003c\/td\u003e\n\u003ctd class=\"co\"\u003eHigh-Grade Engineering Plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCheck Valve Design\u003c\/td\u003e\n\u003ctd class=\"ct\"\u003ePrecision Piston-Style\u003c\/td\u003e\n\u003ctd class=\"co\"\u003ePrecision Piston-Style\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd class=\"ct\"\u003e40+ PSI\u003c\/td\u003e\n\u003ctd class=\"co\"\u003e40+ PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDurability\u003c\/td\u003e\n\u003ctd class=\"ct\"\u003eMaximum Long-Term Reliability\u003c\/td\u003e\n\u003ctd class=\"co\"\u003eEnhanced Over OEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd class=\"ct\"\u003eTrack\/High-Boost\/Extreme Duty\u003c\/td\u003e\n\u003ctd class=\"co\"\u003eStreet\/Stage 1-2\/Cost Effective\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"tgk-section\"\u003e\n\u003cdiv class=\"tgk-sh\"\u003e\n\u003cdiv class=\"tgk-ic\"\u003e\u003csvg viewbox=\"0 0 24 24\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath d=\"M13 2L3 14h9l-1 8 10-12h-9l1-8z\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv class=\"tgk-sh-title\"\u003eFeatures \u0026amp;
