The Integrated Engineering 1.8T longitudinal intake manifold was carefully designed to retain all of your factory components while delivering industry leading performance. Through extensive research and development, this intake manifold fits both 058 and 06A longitudinal engine bays. Unlike other manifolds on the market, the IE 1.8T longitudinal intake manifold does not require you to modify any portion of the cooling/fueling system, PCV sensors, or brake booster lines. Both large and small port options are available as well as throttle body size options.

Using the latest in Computational Fluid Dynamics (CFD) software, our engineers have optimized the manifold's airflow and power range for virtually any turbo charger. The largest power gains will be seen on setups using a GT28-30R/EFR 6255 or larger turbos, however due to the unique plenum and runner design even aggressive K04+ sized turbos will see gains throughout the RPM range. The pictured power graph is the final testing performed on a 2.0L stroker engine at 12 psi boost level. As you can see, this manifold shows excellent power gains through the mid-high range and very little low end power sacrifice with maximum gains of 80 HP on this set up.

Our plenum design has been generously sized and shaped to optimize and distribute airflow evenly to all 4 cylinders. A plenum design is only as good as the runners attached to it, so we carefully tune the intake manifold runner lengths and diameters. Dramatic power and torque increases come from making small changes to the runner design. CFD software is also used to research and develop an optimized velocity stack (bellmouth) design. Our engineers are equipped to research and test many designs. They found this manifold performs very well when used with a specific bellmouth shape that is flush with the plenum floor.

Each manifold is cast, machined, inspected and packed all in the USA by a major OE supplier. The 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 perfect fit, finish, and maximum value. Your intake manifold is available with a machined throttle body flange to accept a 60mm (stock), 70mm (S4), or Hemi 80mm throttle body. Optional hardware allows you to retain 058 AEB drive by cable throttle body and the cruise control components. (larger than stock throttle bodies such as the 70mm & 80mm will require specialized tuning, contact your tuner for more info)

VW 1999 - 2005 B5 Passat 1.8T

B5 FITMENT

This intake manifold has been carefully designed to fit all B5 longitudinal VW/Audi 1.8T engines. Available with a machined throttle body flange to accept a 60mm (stock) or 70mm (OBD2 VR6) throttle body. On 058 engines, optional hardware allows you to retain the drive by cable throttle body.

B5 FITMENT NOTES:
-Cruise control cannot be used on drive-by-cable cars. This will not effect drive-by-wire cars.
-Using larger than stock throttle bodies such as the 70mm & 80mm will require specialized tuning.

 

B6 FITMENT

This intake manifold has been carefully designed to fit all B6 longitudinal VW/Audi 1.8T engines. Available with a machined throttle body flange to accept a 60mm (stock), 70mm (2.7T S4), or Hemi 80mm throttle body.

B6 FITMENT NOTES:
-B6 chassis AMB engines require the use of IEBAUU3 IE 12mm Injector Extensions (sold separately) if used with stock sized 48mm injectors with stock fuel rail. If using long style aftermarket injectors or IEFUVA1 IE billet fuel rail, injector extensions are not required.


FAQ:

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?
We have included vacuum fittings and vacuum line to provide connections for all needed accessories. We also offer a full sized stealth vacuum manifold with more ports if needed for your setup.

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 throughout the entire rpm range when compared to any of the competing manifolds. Vacuum ports have been placed on the underside of the intake manifold so there are no ugly vacuum ports visible on the top of the manifold. We believe this makes our manifold the most visually appealing piece on the market as well as the first manifold available as a direct fit with no modifications needed on both B5 and B6 chassis.

I see that the intake manifold is large-port only. Can I use this on my small port 1.8T head?
For all longitudinal small port heads, purchase IE intake manifold IEIMVA3.

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 powdercoat finish Is there a benefit to the black finish?
The black powdercoat finish is NO LONGER available!
How do I know if my cylinder head is 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 longitudinal engine codes are the large port heads, all other codes are small port and require IEIMVA3 intake manifold to be purchased instead.

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.

Soft, fluffy and surprisingly comfortable
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
I really liked these pillows. I tried to show different things in my photos because I wanted people to see the details: the design, how fluffy they are, and how full and thick they actually look. They are so full that the pillowcase even looks tight once you put it on, which I actually loved because they look luxurious and well-filled. At first glance they look very thick and high, but once you lay down they feel soft and fluffy instead of hard. They adjust comfortably and feel very cozy whether you’re sleeping, relaxing, or even reading before bed. I think they offer a really good balance because they feel supportive without being stiff. Of course, pillow preference is very personal—some people like lower pillows and others like higher ones—but for someone who likes fuller pillows that are still soft and comfortable, these are great. They are spacious, cozy, and feel like a very good purchase overall. I honestly don’t have any complaints so far. Definitely happy with them.

Great quality pillows. Very difficult wrapping.
Color: White, Size: King (Pack of 2)
The Pillows are the real deal. Very fluffy but with good support. I was surprised by the weight of the box they came in, pretty heavy so you know there’s good quality pillows inside. The one negative is that the pillows are packed in very very tight plastic because they come compressed. But the thing is, it’s really a chore to open them. You have to be careful not to cut through the plastic to the material, but the plastic is put on so incredibly tight that it’s even hard to get your finger underneath. But I found a way to open them. Near the top, insert A very flat metal ruler as far in as you could get it. Then cut through the plastic that’s above the metal ruler. That prevents a sharp tool from damaging the pillows. As you get through the plastic above the ruler, keep pushing the ruler further down into the package. Believe me, this simplifies what could be a very difficult unpacking. I am very surprised that the company that makes them does not insert the type of opener that you find on boxes you receive in the mail or even packages that you get from the grocery store where you just pull a tab and that opens the package. These are really good pillows, but you must be very careful about using a sharp object when opening the box and when trying to cut through the plastic. I am a strong man and have the tools needed, a very flat metal ruler, and a box cutter, knife, or razor. Good luck. !!

These hold up very well
Color: White, Size: Standard (Pack of 2)
I have NO luck with pillows. I’ve been in stores & tried them. They seemed ok there. At home, nope. I’ve been getting headaches & neck aches from lousy pillows. I’ll change one, a few nights relief. It doesn’t help that I’m prone to headaches. After reading about different pillows, I settled on these. The reviews were better than so many different ones I was looking at. Including high priced & brand names. I bought the standard size. When I saw, “Customers Usually Keep This”, I kept my fingers crossed. When I received them, I took one out of the package & put my head on it & thought, oh no! This is too hard! I tried it again. Ok….. I slept on it & haven’t had any pains since. It’s soft but firm enough to keep my head from sinking & messing up my neck. I don’t move. No more flipping my pillow over. My head doesn’t go below my neck anymore! This has been 2 months now, but it hasn’t changed at all. I wake up happy, not complaining. No more pains or headaches. This saved me from losing days with a heating pad or an ice pack. The price was excellent for 2 pillows. I can’t believe a blind buy was the answer! These are incredible. Finally, something worked for me.

Awesome Pillows!
Color: White, Size: King (Pack of 2)
These pillows are super soft! I love them. I bought them when I caught a bad cold and needed to prop myself up. Worked so great! Definitely give these pillows a try. They're very reasonably priced too.
