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
FAQ
What is the benefit of a modular plenum?
The two-piece manifold can be easily flipped to put throttle flange on either side, easily adaptable to any big turbo setup.
What kind of power gains will I see?
Power increases are seen in mid-high rpm ranges, depending on turbo setup and displacement.
What else will I need to install?
Intake manifold now includes our micro vacuum manifold to provide connections for all needed accessories. We also offer a full sized stealth vacuum manifold with more ports if needed for your setup. If using our intake manifold on a small port head, we offer a phenolic transition spacer, which makes the connection between the two without any flow-reducing “steps.”
Will I need tuning for this manifold?
For maximum performance, tuning is recommended. However, if the factory throttle body is used, it is not absolutely necessary. If upgrading to a larger throttle body, tuning is a must.
How does the IE intake manifold compare to others on the market?
Our intake manifold shows the best gains in the mid-high rpm range when compared to any of the competing manifolds. By utilizing our micro vacuum manifold, there are no ugly vacuum ports visible on the top of the manifold, regardless of the plenum orientation. We believe this makes our manifold the most visual appealing piece on the market as well as the first manifold available with the modular plenum design. This makes it versatile, as it can be installed with any intercooler piping/throttle body setup.
I see that the intake manifold is large-port only. Can I use this on my small port 1.8T head?
Absolutely! You can easily install our manifold on your small port head with use of the IEBAVA16 phenolic transition spacer.
Is it necessary to upgrade my fuel rail to install this manifold?
Our manifold was designed to work with the factory fuel rail, without modification required. We do offer a high-flow billet fuel rail for higher horsepower applications, which is also visually desirable.
I see that you offer the manifold in raw and black powder-coat finish. Is there a benefit to the black finish?
The black powder-coat finish is not only visually appealing, but it is much easier to keep clean. Raw cast aluminum parts easily collect dirt that is difficult to remove. The powder-coat finish does not show dirt easily and can be easily cleaned.
How do I know if my cylinder head is a small port or large port?
The 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 are the large port heads, all other codes are small port and require the IEBAVA16 phenolic transition spacer to be used.
