Intake is very complete – comes with everything you need (except for the tools, obviously). You don’t need to stop at the auto parts store for anything else. No cutting, modifying, jury rigging anything. aFe clearly did their homework when they designed their intake. Having first used their intake on my Ford Superduty 7.3L Powerstroke 14 years ago, I was sold on their fit, finish, and performance. I’m glad to see they have reinvested back into the company with solid engineers to design a system for our Jeeps.
Here is Momentum GT unpacked from the box.
To note – aFe is on top of their quality game. Each kit is inspected by a quality control person, as noted by the tag:
With the filter media – there are options. The Pro 5 S dry (white), or the Pro 5 R oiled (blue)
The engine bay, which should be a familiar sight:
The future home of the intake:
Step 1 – remove the engine cover. Just pull straight up.
Unbolt the resonator box that leads into the throttle body.
On the back of the resonator box, be sure keep the air intake temperature sender. You’ll need it later. A quarter turn and it’ll pop out.
Use a body clip tool to carefully remove the three clips surrounding the intake area of the airbox:
Once that’s free, pull the OEM airbox out. It is held in by three rubber grommets. There is a zip tie affixed to the back of the airbox you’ll need to unclip. Pull up hard.
Remove the three rubber grommets, and move them to the aFe box.
I chose to use the oiled filter – so slide it into the intake box:
Run the band clamp around the box, after you’ve inserted the filter. Then push the filter box back into OEM location:
Slide the boot onto the throttle body, with a clamp on each side of the hump:
Grab the intake air temperature sensor, and insert that, with the rubber grommet, into the back side of the intake tube:
Slide the intake tube into filter:
Slide the other end into the boot:
Plug in the PCV hose, as well as the intake air temperature sensor wiring. Note, that the tube is molded such that it clears the air conditioning line.
Last – put the engine cover back on!
And the most important part – how all the HP is made – the STICKER.
Here’s my back to back testing using the Torque Pro App:
