ECS Tuning Build-Your-Own ECS Tuning 2.0T FSI/TSI Aluminum Intake Manifold Kit

The ECS Tuning Fabricated Aluminum Intake Manifold for the EA113 FSI and EA888 Gen1 TSI engine provides even air flow distribution to all four cylinders due to its 53% larger plenum volume over the stock manifold, parabolic velocity stacks, and reconfigured plenum geometry. If you've upgraded to a larger turbo and you're looking to take your build to the next level, the ECS Aluminum Intake Manifold is for you! This is the perfect foundation for balanced airflow and will increase top-end charge to maximize your engine's efficiency.

The OEM plastic intake manifold suffers from cylinder imbalance by up to 5% between runners. The result is uneven cylinder filling within the outer runners, causing variations in air/fuel ratios. Our intake manifold equalizes this flow imbalance without sacrificing any efficiency, providing a flow balance with less than 0.5% deviation. To further increase airflow, our design eliminates the factory air dividers. All together, these modifications resulted in a sizeable gain of +8% CFM over the factory FSI and Gen1 TSI intake manifolds.

Our Engineering Team at ECS Tuning sought to make the best intake manifold available on the market. Rather than designing a cast manifold, they took a different approach. This meant engineering a billet and fabricated aluminum sheet design, featuring 5-axis CNC-machined aluminum mounting flanges and billet CNC intake runners. This design provides an optimal flow path and smooth transitions from the parabolic velocity stacks inside the plenum to the intake port shape. This allowed us to achieve the smoothest airpath possible, favored over the rough casting marks found in traditional cast designs. The billet runners feature 1/8" NPT ports, ready to accept nitrous or water/meth injection nozzles. The 5052 aluminum sheet plenum houses precision-machined velocity stacks, while also increasing plenum volume 53% over the factory manifold for increased throttle response and improved cylinder filling.

DESIGN

• Cylinder Head Flange:
  • 5-Axis CNC machined from 6061 aluminum
  • 100% compatible with the OEM fuel rail, fuel rail bracket, and injector wiring harness with no modifications or trimming required
• Intake Runners:
  • 5-Axis CNC machined from 6061 aluminum to provide equal runner velocity and optimal interior surface finish
  • Designed to provide an optimal flow path and super smooth transitions between the plenum flange and head flange
  • Secondary fueling/cooling/nitrous nozzle bosses are pre-machined atop each intake runner for direct port water/meth injection or nitrous nozzles
    • ​Pipe plugs are included in the installation kit to block these off if desired
• Plenum Flange:
  • 5-Axis CNC machined from 6061 aluminum
  • Features parabolic velocity stacks, which provide smooth airflow into each intake runner
• Intake Plenum:
  • Formed from 1/8" thick 5052 sheet aluminum
  • 53% larger plenum volume (2.47 Liters) promotes even air flow distribution to each runner while promoting consistent cylinder filling
• ​Throttle Body Flange:
  • CNC machined from 6061 aluminum​
  • 70mm throttle body opening; features a radiused outlet for smooth airflow entry into the plenum
  • Compatible with OEM throttle body
  • Incorporates NPT vacuum ports in front and passenger side locations
  • Various pipe plugs and nipple fittings are included to accommodate custom setups
• Final Assembly:
  • Wrinkle black powder-coated finish
  • Fabricated and TIG-welded by expert fabricators
  • Tested to 0% leak down at 3 BAR for final quality

PERFORMANCE

• ​Our intake manifold provides even air flow distribution to all four cylinders due to its 53% larger plenum volume over the stock manifold, parabolic velocity stacks and reconfigured plenum geometry
  • Stock 2.0T Gen1 plenum volume: 81 in.³ (1.33 Liters)
  • ECS plenum volume: 151 in.³ (2.47 Liters)
• Provides the necessary foundation for supporting modifications such as a larger turbocharger, more efficient intercooler, and free-flowing intake and exhaust upgrades, along with custom ECU tuning.
• Tested on our in-house Superflow Flow Bench, we recorded a +3 to +8% increase in CFM over the factory 2.0T Gen1 manifold. Particularly, runners #1 and #4 found a +6 to +8% increase in airflow by up to 15 CFM.
• The OEM plastic intake manifold suffers from cylinder imbalance by up to 5% between runners. Our intake manifold equalizes this flow imbalance without sacrificing any efficiency, providing a flow balance with less than 0.5% deviation.
• Our design does not incorporate intake runner air guides for improved airflow.

PRODUCT DEVELOPMENT

Our ECS Fabricated Aluminum Intake Manifold was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. After several design iterations, multiple prototypes, and multiple vehicle test fitments, we are proud to offer a truly remarkable intake manifold to the VW/Audi enthusiast market!​
