NBGZJYT PCV Valve Oil Separator Kit for Audi 2.0L — Crankcase Breather Hoses, OE-Fit Durable

NBGZJYT PCV valve engine crankcase oil separator with breather hoses restores proper crankcase ventilation and helps protect 2.0L Audi engines from oil blow-by and sludge buildup.

This replacement kit includes a precision-molded oil separator and two matching breather hoses engineered to match OE fitment for many Audi 2.0L turbocharged applications. Built from heat- and oil-resistant materials, the assembly helps re-establish the designed flow of crankcase gases back to the intake, reducing oil carryover and helping maintain engine cleanliness when installed correctly.

Which Audi models and years will this kit fit?

The NBGZJYT kit is made to be compatible with a range of Audi 2.0L four-cylinder models across model years. Verify your vehicle by checking engine type and OE part number before purchase to ensure exact compatibility.

• Fits Audi A5 (2012–2014), A5 Quattro (2012–2017) 2.0L L4
• Suitable for Audi A6 (2012–2015), A6 Quattro (2013–2015) and select Q3/Q5/Allroad 2.0L models (2012–2018)
• Cross-references OE numbers: 06H103495AE, 06H103495J, 06H103495AK; aftermarket ref: URO013463, V103320

How does replacing the oil separator and hoses benefit engine performance?

Replacing a worn or clogged oil separator and breather hoses restores the intended crankcase ventilation path, reducing oil contamination of the intake and lowering the risk of sludge formation. This helps the engine run closer to original specifications and can prevent performance-robbing deposits.

• Reduces oil vapor entering intake tract and intake-valve deposits
• Helps maintain proper PCV flow and combustion efficiency
• Prevents excessive crankcase pressure that can cause oil leaks

What are the construction and durability details of this replacement kit?

The kit uses engine-grade materials designed to tolerate high under-hood temperatures and constant oil exposure. Quality-molded connections and reinforced hoses improve longevity versus degraded factory components, supporting reliable operation under normal driving conditions.

• Oil separator built for oil- and heat-resistant durability
• Hoses molded to resist collapse and hardening over time
• Fitment focused on direct replacement for easy installation

What’s included and how easy is the installation?

The package delivers everything needed to replace the separator assembly: one oil separator plus two breather hoses. The components are designed for direct swap with the original parts; basic hand tools and standard mechanical knowledge are sufficient for most DIY jobs.

• Included: oil separator x1, breather hose exhaust pipe x2
• No printed manual included; typical install uses OE mounting points and clamps
• Recommended: inspect clamps and connecting components and replace if brittle

Who this is for: This kit is aimed at Audi owners and independent mechanics who need a cost-effective, OE-referenced replacement for a failing PCV/oil separator system on 2.0L Audi engines. It's well suited for routine maintenance, restoring ventilation function after clogging, or when symptoms like oil consumption, intake contamination or crankcase pressure indicate a compromised separator or brittle hoses. Always confirm part numbers and fitment before ordering and consider professional installation if unsure.
