034Motorsport X34 Carbon Fiber Open-Top Air Intake System for MQB Vehicles

The X34 Carbon Fiber MQB Open-Top Cold Air Intake System for 8V/8S Audi A3/S3/TT/TTS, MkVII VW Golf/GTI/R & MkVII VW GLI equipped with 1.8T/2.0T Gen 3 engines has arrived! We listened to customer feedback and this open-top design allows more intake tract sounds to be heard at a louder volume. Offering dyno-proven peak gains of up to 15 crank horsepower and 12 ft-lbs of torque on a completely stock vehicle, and over 30 crank horsepower and 25 ft-lbs of torque on vehicles equipped with Stage 1/2 Performance Software, the X34 Intake System is the ultimate induction solution for your Audi or Volkswagen.

034Motorsport’s engineers thoroughly evaluated the factory airbox design to create a performance replacement that reduces pressure drop in the intake tract, while offering OEM+ fit and finish. The result is this complete one-piece MQB Carbon Fiber Air Intake Upgrade, which offers 100% bolt-on installation without the need for any additional pieces.

034Motorsport engineers started by identifying the shortcomings of the factory intake system to determine which components restricted airflow to the turbocharger inlet. While the factory lower airbox and fresh air duct to the core support were more than sufficient for increased power levels, the factory air filter, upper airbox, and turbo inlet tube were deemed too restrictive, even with the factory turbocharger.

034Motorsport's mechanical engineers scanned the factory engine bay and modeled a one-piece unit to replace the factory intake tube and upper airbox. By eliminating the multiple couplers, transitions, and jagged features in the factory upper airbox and intake tube, 034Motorsport's engineering team was able to drastically reduce turbulence in the intake tract, and virtually eliminate pressure drop in the intake system before the turbo inlet.

Multiple iterations were prototyped in plastic using 034Motorsport's in-house FDM 3D printer and thoroughly tested. Ultimately, the best-performing design featured a massive 4" inlet at the air filter and a large-diameter one-piece intake tube with smooth transitions all the way back to the factory turbo inlet.

034Motorsport focuses on optimizing every aspect of the intake system across a broad range of variables and compromises. A critical component of a high-flowing performance intake is the ability for air to flow around and into the filter. If the air cannot flow freely around the filter, it will be restricted from getting into it. Many aftermarket kits fit too large of a filter in an enclosure that cannot accommodate its size, thus choking the filter and reducing its overall flow. This often happens when a product is engineered for one variable at the expense of others. 034Motorsport conducted extensive tests and refined its development of the intake design to allow for maximum airflow surrounding the air filter, allowing for optimal airflow to, and through, the filter. The final result is the right size filter in the right size filter housing, creating maximum airflow and performance with OEM level filtering; the ultimate goal of any intake system. Be cautious of any intake that brags only of air filter size, without taking into account the detrimental effects of shrouding the filter.
