{"product_id":"pcv-breather-hose-9","title":"PCV Breather Hose","description":"Upgrade your factory corrugated plastic, failure-prone PCV breather hose with the high-performance, reliable 034Motorsport PCV Breather Hose. Engineered for enhanced durability and long-lasting performance, this hose is a critical safety enhancement for all EA839-equipped vehicles.\n\nThe PCV (Positive Crankcase Ventilation) system on the EA839 engine is vital for managing crankcase pressure. The factory breather hose contains check valves that switch between ventilation pathways to prevent crankcase vacuum loss or boost pressure entry. However, these OE components are prone to premature failure. When they fail, the crankcase can pressurize, potentially leading to hot oil escape, engine damage, and even fire risks. Audi issued a TSB regarding this failure, and testing shows even the newest OE hoses can fail.\n\nThe 034Motorsport PCV Breather Hose features proprietary check valves engineered for superior flow and sealing capabilities, capable of handling over 40 PSI and high engine bay temperatures. The hose itself is constructed from high-flow, 4-ply reinforced and fluorolined silicone, designed to prevent collapse under vacuum or boost and to resist oil vapor sweating. This design ensures reliable crankcase ventilation for EA839 V6 engines across all power levels, from bone stock to Stage 3 tuning.\n\nInstallation is described as mild and straightforward, taking approximately one hour. The hose retains the factory engine cover and uses OE-style connections for easy installation and removal. This upgrade offers a long-lasting solution, eliminating the need for costly OEM replacements which often include the entire turbo inlet system. The product is sold for racing use and for vehicles not registered for on-highway use; it is not legal for street vehicles.","brand":"034motorsports","offers":[{"title":"Default Title","offer_id":52686644740408,"sku":"034-101-3108\/09","price":249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687883487.jpg?v=1784875587","url":"https:\/\/store.motormia.co\/products\/pcv-breather-hose-9","provider":"MOTORMIA","version":"1.0","type":"link"}
