Fully TIG welded with precise settings to produce optimal penetration without impacting airflow.
Significant drop in EGT's due to better equalized airflow to cylinders 1, 5, and 6.
Fuel mileage increase
Increased throttle response
Faster turbo spool
1.
Why do I need the Cross-Air?
Achieving balance air and fuel delivery
extremely important to the life and power deliver of any engine at any power
level. The inline Cummins engines found in the Dodge/RAM trucks are well known
to run hotter in the back cylinders and those cylinders are most common to
fail. The Cross-Air is by far the easiest and most cost effective way to
achieve more balanced air delivery.
2.
How does the Cross-Air work?
At the front and back of the 24v cylinder
head’s plenum is an inspection port that is plugged off at the factory with the
same style plug used as freeze plugs in engine coolant applications. When you
remove these plugs on the cylinder head and look inside, you’ll be staring
directly at the #1 and #6 intake port. Thus by routing air via parallel flow
paths (the Cross-Air) to these ports you’ll help decrease pressure loss across
the head by feeding your intake ports in “series” off of a poorly designed
plenum. A very simple comparison is feeding live stock in a feeding trough. If
you dump grain in one spot (inlet to the cylinder head where the intake
manifold attaches) in the trough (plenum) the animals at either end (cylinders
1 & 6) are not going to get as much food as the ones nearest the grain
source.

How does the Cross-Air attached to the head?
The Cross-Air come with a CNC machined
billet adapter that is pressed into the inspection port just like the plug that
came out.
4.
Do I need to remove my cylinder head to perform
the install?
No, this setup is intended to be installed
while the motor is intact in the truck. Having your cylinder head off does
obviously make things easier but is not necessary.
5.
Will the Cross-Air worth with a stock intake
manifold or aftermarket intake manifold?
Yes, it is designed to work with the factory intake manifold and any manifold
designed to directly replace the stock manifold. Check out our combo deal where
you can purchase a Pusher manifold and the Cross-Air.
6.
Does this setup work with dual CP3’s?
That depends on the design of the bracket
that holds the second CP3. Sometimes the second CP3 hangs down in front of the
front port making good access to it
impossible. In this case we can build a custom Cross-Air that just delivers air
to the rear port which is the most critical.
7.
How long is the install procedure?
We recommend a few hours or more depending on your
familiarity with your truck.
8.
How much HP will this add?
That depends on how much air you’re trying to
move through it. The more air you’re moving the more power there is to be
gained.
Nice Product!
