Description
Unleash the full performance of your VW/Audi 1.8T 20V engine with the Integrated Engineering (IE) Intake Manifold Kit, designed specifically for transverse applications using a 60mm throttle body. This manifold is engineered from the ground up as a true motorsport solution, offering dramatic horsepower and torque improvements across the entire rev range.
Unlike stock manifolds, which restrict performance beyond factory tuning, the IE 1.8T manifold uses resonance-tuned runners and velocity stack bellmouths to force more air into the combustion chamber, improving power, responsiveness, and top-end efficiency. Ideal for GT28+ turbo builds, this manifold provides dyno-proven gains of up to 90+ HP with minimal compromise to low-end spool.
Key Features
-
Motorsport-Engineered Design – Designed for maximum flow and efficiency
-
Up to 90+ HP Gains – Optimized for GT28 or larger turbo setups
-
Modular Reversible Plenum – Enables flexible throttle body placement
-
Velocity Stack Bellmouth Runners – Enhance mid and high-RPM airflow
-
Minimal Turbo Lag – Balanced design for power and spool retention
-
Precision-Cast in the USA – High-strength alloy, CNC-machined surfaces
-
Black Powder-Coat Finish – Durable, sleek, and corrosion-resistant
-
Includes IE Micro Vacuum Manifold – Clean and efficient vacuum routing
Performance Advantage
With extensive use of Computational Fluid Dynamics (CFD) and real-world dyno testing, IE’s intake manifold maximizes cylinder fill and airflow delivery. The runner geometry, plenum size, and bellmouth transitions are all meticulously optimized to support aggressive boost levels and high horsepower demands.
Vehicle Fitment
This manifold is a direct upgrade for transverse-mounted 1.8T 20V engines with large-port or small-port heads (adapter required):
-
Audi TT (MK1 – 8N): 2000–2006
-
Audi A3 / S3 (MK1 – 8L): 1996–2003
-
VW Golf / GTI (MK4): 1999–2005
-
VW Jetta / GLI (MK4): 1999–2005
-
VW Beetle (1C/9C/1Y): 1998–2011
Note: Some vehicles may require relocation of the washer fluid reservoir and custom intercooler piping due to space limitations.
Required Hardware
-
IE Phenolic Adapter Kit – Required for small-port cylinder heads
-
60mm Throttle Body Compatible – Designed for use with 60mm throttle body setups
