ECS Tuning B6 A4 1.8T Performance Baffled Oil Catch Can System - 8 oz.

Say goodbye to oil-soaked intakes and carbon-clogged valves with the only plug-and-play catch can system on the market!

The Positive Crankcase Ventilation (PCV) system plays a vital role in managing engine blow-by gases, reducing emissions, and regulating crankcase pressure. On the B6 A4 1.8T, the factory PCV components are known to wear out over time, leading to cracked lines, stuck valves, and internal leaks. When this occurs, excess oil vapor from the crankcase ventilation system can accumulate inside your intake tract, coating the intake manifold and intake valves in sticky, oily residue. The result? Increased oil consumption, erratic idle, loss of boost, and reduced power.

The ECS Tuning Performance Baffled Oil Catch Can System is a performance-focused upgrade that addresses these issues at the source. Through intensive research, our engineers found two critical flaws in the 1.8T's factory PCV system—weak rubber and plastic construction used for plumbing, and poor oil separator circulation. To solve these issues, our kit incorporates high-quality silicone hoses for plumbing and a strategically positioned four-chamber baffled catch can. This precision-engineered system intercepts and traps oil vapor before it can enter the intake system, significantly reducing oil buildup on the back of intake valves, preserving your engine's performance, efficiency, and longevity.

Constructed from black anodized 6061-T6 billet aluminum, our catch can is fully serviceable thanks to the included knurled dipstick and drain kit. Our plug-and-play kit includes a sheet metal bracket to tie the can to the left side frame horn, providing easy installation and even easier access. Easy to install, reversible, and built to last, this is the ultimate PCV upgrade for your turbocharged Audi!
