Description

ENHANCE YOUR MANIFOLD FOR OPTIMAL AIRFLOW. Achieve unparalleled power and torque throughout the entire rpm range with the sole motorsport-engineered intake manifold designed specifically for your transverse 1.8T 20V engine.

ADVANTAGES OF THE INTAKE MANIFOLD The stock intake manifold is crafted to direct air into the engine adequately to meet factory horsepower levels, leaving considerable room for improvement in performance builds utilizing larger-than-stock turbochargers. IE’s 1.8T 20V intake manifold stands out as a genuine performance design, incorporating key motorsport features. Precise tuning of intake manifold runner lengths, diameters, and bellmouths collaborates to force more air into the cylinders. Through computer software optimization, the plenum and runners are fine-tuned for maximum flow. This specialized design results in a leading-edge intake manifold capable of delivering gains of over 90HP!

POWER BOOST Carefully engineered and dyno-tested, this intake manifold yields optimal power results under any conditions. Thanks to the unique plenum, velocity stack, and runner design, setups with GT28 or larger turbos will experience gains across the mid-high RPM range with minimal sacrifice in low-end power.

FLEXIBLE THROTTLE BODY PLACEMENT IE intake manifold’s modular plenum design allows the throttle body to be positioned on either side of the engine bay. The entire plenum can be disconnected from the runners and flipped in either direction, facilitating easy installation with minor adjustments for virtually any turbo setup.

VELOCITY STACK BELLMOUTH RUNNERS Utilizing specialized engineering software, we researched and developed an 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.

MINIMIZED TURBOCHARGER LAG The IE manifold strikes a perfect balance between power gains and minimizing spool time and low-end power loss. Depending on the engine and turbo setup, the manifold typically results in minimal added turbo lag compared to other manifolds with similar-sized runners and plenum.

CRAFTED, CAST, AND MACHINED IN USA.

IE manifolds are cast from a unique self-aging, self-hardening alloy with stringent requirements for chemical composition. State-of-the-art Japanese machining centers handle all major surfaces of the parts in one setup, ensuring a flawless fit, finish, and a lifetime of service.

IE MICRO VACUUM MANIFOLD This manifold includes the IE micro vacuum manifold at no additional cost. This small anodized fitting provides all the necessary vacuum sources without cluttered lines. Its quick and easy installation offers a sleek and clean solution for plumbing your blow-off/diverter valve, boost gauge, fuel pressure regulator, brake booster, or any other component requiring a vacuum source.

FAQ

What are the advantages of a modular plenum?
The two-piece manifold can be effortlessly flipped to position the throttle flange on either side, making it adaptable to any substantial turbo setup.

What kind of power gains can I expect?
Power increases are observed in the mid-high rpm ranges, contingent on the turbo setup and displacement.

What else is necessary for installation?
The intake manifold includes the IE micro vacuum manifold to offer connections for all required accessories. A full-sized stealth vacuum manifold with more ports is also available if needed for your setup. When using the intake manifold on a small port head, the IEBAVA16 phenolic transition spacer is offered, establishing a seamless connection between the two without any flow-reducing “steps.”

Is tuning required for this manifold?
For optimal performance, tuning is recommended. However, if the factory throttle body is utilized, it is not strictly necessary. Tuning becomes imperative when upgrading to a larger throttle body.

How does the IE intake manifold differ from others in the market?
The IE intake manifold exhibits the most significant gains in the mid-high rpm range compared to any competing manifolds. Utilizing the IE micro vacuum manifold ensures no unsightly vacuum ports are visible on the top of the manifold, regardless of plenum orientation. This design feature makes our manifold not only visually appealing but also the first manifold with the modular plenum design. Its versatility allows installation with any intercooler piping/throttle body setup.

I notice that the intake manifold is large-port only. Can I use this on my small port 1.8T head?
Certainly! Our manifold can be easily installed on your small port head with the use of the IEBAVA16 phenolic transition spacer.

Is it necessary to upgrade my fuel rail to install this manifold?
The manifold is designed to work seamlessly with the factory fuel rail without requiring modification. However, for higher horsepower applications, IE offers a high-flow billet fuel rail that is both functionally and visually desirable.

How do I determine if my cylinder head is a small port or large port?
Cylinder heads are stamped with the three-letter engine code on the front corner, near the #1 cylinder. Only the AEB and AGU engine codes indicate large port heads; all other codes represent small port heads and require the use of the IEBAVA16 phenolic transition spacer.
