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)

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.

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

I’m a little disappointed.
Format: Kindle
I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic. I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop. One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.
