ECS Tuning Big Bore Cast Aluminum Turbo Inlet Pipe - B9 S4/S5 3.0TAll too often OEM components sacrifice performance in an effort to appeal to a wide variety of customers. While an enthusiast typically wants better boost response and more power, all while hearing the turbocharger breathe, a non enthusiast may give up these characteristics for a quieter ride.

All too often OEM components sacrifice performance in an effort to appeal to a wide variety of customers. While an enthusiast typically wants better boost response and more power, all while hearing the turbocharger breathe, a non-enthusiast may give up these characteristics for a quieter ride. Give your 3.0T Audi B9 S4 or S5 the performance it deserves and engage with your car for a more enjoyable driving experience! 

In the case of the factory turbo inlet pipe, mounted between the compressor housing and air intake hose, its purpose is to channel air from the inlet hose into the turbocharger inlet, all while reducing engine bay acoustics and sacrificing quality materials in favor of cheap molded plastic material. With the ECS Big Bore Turbo Inlet Pipe, the factory inlet pipe is removed and replaced with our straight-through, high flow cast aluminum inlet. This increases available airflow and turbocharger sound by creating a larger, smoother transition between the turbo inlet hose and compressor housing inlet. To top things off, the flange and bungs are TIG welded, machined billet aluminum to ensure longevity, strength, and dimensional accuracy.  

Key features: 

  • Cast aluminum construction

  • 55mm ID at the turbo inlet to maximize air flow (compared to stock 52.2mm) with an 11% increase in area

  • 66mm ID at the intake elbow

  • Retains factory PCV return and wire loom anchors

  • Machined billet flange and bungs for a precision fit and durability 

  • Oil resistant o-ring and stainless hardware included

 

Performance:

  • Increased bore diameter for increased flow and reduced restriction to the turbo

  • At -20 in Hg test pressure, the stock inlet has a flow rate of 327 CFM vs the ECS inlet which has a flow rate of 382 CFM, a 16.8% increase in flow rate over the stock plastic inlet!
