Jeep Wrangler JL 2.0L Turbo Performance Intake 2018+

It's the challenges that make life exciting. Doing the same thing over and over gets tedious, but if you seek out challenges, life begins to get interesting. When we last talked about our 2018+ Jeep Wrangler 2.0L intake, things were starting to get very interesting.

The last post saw our prototypes hitting the dyno to see if our efforts had paid off. Despite a 20% increase in flow over the stock intake, there was no massive improvement in power with either prototype. Both prototypes did let out a little more sound from the turbo, however. While the lack of power increase wasn't surprising (as explained in the last post), looking at the resulting dyno graphs did show an unexpected trend. Though peak power didn't increase or decrease compared to the stock intake, it did move later in the RPM range. Much later.

We've reached a massive milestone in the development of our 2018+ Jeep JL 2.0T intake. After months of measuring, testing, printing and waiting, we finally have a functional prototype. Although it's been a long road to get to this point, the development of this intake has also been a breath of fresh air; we're trying a lot of new techniques and exploring new R&D methods. But before we jump into what's new, let's look at what brought us to this point.

We began developing our intake by looking at the stock intake. Our engineer, Ye, filtered through all the components to find what needed to stay and what we could improve. She 3D scanned and meticulously measured every inch of the stock intake and the JL's engine bay. Later, a flow-bench test of the stock intake gave us a baseline to compare our design to. With measurements, 3D scans and testing of the stock intake complete, we began building our prototypes.

Sometimes the long road is the path we take when we want
to slow down, take a deep breath, and enjoy the view. Sometimes the long road
is the path we take when we want to do something well. While we love watching
the development process unfold, we're taking the long road to our 2018+ Jeep
Wrangler JL 2.0T performance intake for the latter reason.

"Quality over speed" is our motto for many of our
projects, but in developing complex intakes like the one found on our JL's 2.0L
Hurricane engine, it's a requirement. Rushing through a project like this often
means fighting check engine lights and poor performance. In the end, rushing
takes longer than doing it right the first time.

We've spent the last four months analyzing every detail of the stock Hurricane intake.

We often say that engines are just air pumps. The more
air you can get in and out of them, the more efficient they are, and the more
power they make. While that's true for any engine at its core, computers and
electronic controls tend to complicate the equation. As cars and trucks become
more complex and efficient, the computers controlling them have a hand in
almost every aspect of how they run. Most of those controls focus on how the
engine breathes in through the intake and out through the exhaust.

So, what does that mean for our 2018+ JL 2.0T intake? It
means that "good enough" isn't an option. The sensors attached to the
Hurricane's stock intake and its complex design require precision along every
step of development. It may seem like we're dragging our feet by looking so
closely at the stock intake, but every feature of every component plays a major
role in how the intake functions.

As the weather here in Delaware continues to get colder,
I've resigned myself to only leaving the house to avoid starvation or getting
fired (and it's not even really cold here). As much as I hate the cold, I'm
reminded every morning that my turbocharged car loves it. The only thing better
than cold, dense air for a turbocharged engine is more cold, dense air. Once
the winter months turn into spring and summer, more of us will be out enjoying
the warm air, but your 2.0T Jeep JL will be longing for the cold of winter. At
Mishimoto, we've been working to give your Jeep the cool air it needs to
perform its best all year long.

The first post on our 2018+ JL 2.0L turbo intake focused on every aspect of the stock intake system. If you missed that post, I suggest
