Integrated Engineering - 1.8T Transverse Intake Manifold - TT Mk1

UPGRADE YOUR MANIFOLD FOR ULTIMATE FLOW
Gain market leading power and torque across the entire rpm range with the only true motorsport designed intake manifold available for your transverse 1.8T 20V engine.

INTAKE MANIFOLD BENEFITS
Your factory intake manifold is designed to channel air into the engine just well enough to meet stock horsepower levels, leaving room for significant improvement on performance builds utilizing larger than stock turbochargers. IE's 1.8T 20V intake manifold has been designed as a true performance design with major motorsport features. Optimized tuning of the intake manifold runner lengths, diameters, and bellmouths work together to ram more air into the cylinders. The plenum and runners are optimized with computer software for maximum flow. This very specialized design work results in a market leading intake manifold design capable of over 90HP gains!

POWER INCREASE
Obsessively engineered and dyno tested, this intake manifold delivers the best power results possible in any condition. Due to the unique plenum, velocity stack, and runner design all setups with GT28 or larger turbos will see gains throughout the mid-high RPM range with very little low-end power sacrifice.

EASY THROTTLE BODY PLACEMENT
Our intake manifold allows the throttle body to be installed on either side of the engine bay due to the modular plenum design. The entire plenum disconnects from the runners and can be flipped in either direction allowing you to install the manifold with only minor changes on virtually any turbo setup.

VELOCITY STACK BELLMOUTH RUNNERS
Specialized engineering software was used to research and develop a truly optimized runner and velocity stack design. Aggressively-sized resonance tuned manifold runners and flow tested velocity stacks deliver more air to the cylinder than any other manifold on the market.

REDUCED TURBOCHARGER LAG
The IE manifold provides an optimal balance of power gains while minimizing the loss in spool time and low-end power. Depending on the engine and turbo setup, the manifold will typically result in very little added turbo lag when compared to other manifolds with similar sized runners and plenum.

DESIGNED, CAST, AND MACHINED IN USA
IE manifolds are cast from a special self-aging, self-hardening alloy with especially strict requirements for chemical composition. Top of the line Japanese machining centers machine all major surfaces of the parts in one setup, ensuring a perfect fit, finish, and a lifetime of service.

IE MICRO VACUUM MANIFOLD
This manifold includes the IE micro vacuum manifold at no extra charge. This small anodized fitting provides all of the vacuum sources needed without the worry of cluttered lines. Installs fast and easy, providing a sleek and clean solution to plumb your blow-off/diverter valve, boost gauge, fuel pressure regulator, brake booster, or anything else requiring a vacuum source.

*Fitment may require modification to engine bay components. Due to limited space, windshield washer fluid reservoir relocation and custom intercooler piping may need to be fabricated.

REQUIRED HARDWARE
The manifold is designed for large port and small port cylinder heads. When installing onto a small port cylinder head, we recommend the use of an IE phenolic large port to small port adapter kit. IE part number: IEBAVA16
