No reviews
SKU: 034-108-7001

Manufacturer: 034Motorsport

034Motorsport's Transverse 1.8T High Flow Intake Manifold has finally arrived!

This manifold was designed to be a direct bolt-in replacement for the stock intake manifold, and features a modular design, with a rotatable plenum that allows for driver side or passenger side throttle body locations.

Featuring a 1.85L plenum, the 034Motorsport High Flow Intake Manifold was engineered not only for high-horsepower, big turbo builds, but also to offer noticeable improvements in low-end and midrange power, even on stock turbo configurations.

Features:

  • Manufactured from A356 Using Low-Pressure Die Casting for Superior Quality and Surface Finish
  • High Flow and High Velocity Tapered Runners
  • Large Low-Profile Airhorns and Smooth Plenum Interior for Improved Airflow Characteristics
  • Angled Runners and Indexed Throttle Body Position for Optimal Fitment and Intake Routing
  • "Stealth" Mounting Bosses for Nitrous or Methanol Injection
  • Provisions for Stock or 80mm Throttle Bodies
  • Complete with Vacuum Provisions - No Extra Vacuum Manifold Needed!
  • Available In Large Port and Small Port Configurations
  • Developed in partnership with GRAMS Performance

Please Note: 

  • Though this intake manifold is a direct fit to the 1.8T engine, some small modifications to covers and hose routing may be required, also throttle body position is slightly different than stock and may require a modification to the throttle body inlet hose to fit the stock or our 70mm upgrade. 
  • The small port is the exact same manifold as the large port, and can be bored out for large port applications if desired.
  • The plenum-to-runner bolts should be torqued to 7nm or 62in lbs.
