Upper IC Pipe Install for 2.0L

Time again for another part install. This time, we're replacing the Upper IC pipe on the 2.0L

Here's the car as she sat previously


The upper IC pipe on the left going to the throttle body is plastic. I like a little more metal in my setup, if only for looks. Benefits of upgrading this pipe can include better flow, stronger material (against boost), and a port for meth/nitrous/whatever (if equipped).

Tools are very basic on this job:
Rachet
7mm socket
T20 torx driver or bit
Flat head screw driver (the longer, the better)
Dental pick (optional)

Start by unplugging the electrical connector going to the sensor on the pipe. Pull up on the retainer on top of the connector until it clicks and pull away from the sensor.

Next, loosen the clamp on the lower side of the pipe. A 7mm socket and 1/4" drive ratchet should make quick work here.

Removing the upper pipe from the lower is what took the longest for me, as it just did not want to come apart. Pretty typically any time you're trying to remove a rubber hose that's been clamped down for a long period of time. A dental pick or long flat head screw driver carefully slipped between the plastic upper pipe and lower rubber pipe should help here. Go all the way around it to break the seal. Pull the lower pipe away.

Disconnecting the pipe from the throttle body is easy once you know what you're looking for.



Notice the light gray lock ring at the throttle body. Twist counter clockwise about 10-15 degrees while pulling the pipe away from the throttle body. It should pop right off.

You should now have the old pipe off.



Using your T20, remove the retaining screw for the sensor and swap to the new part. Since mine was tapped for a regular bolt, I used different hardware that the OE sensor, so I tossed the screw back in the OE part in case I had to go back to stock later.

Insert the new pipe into the lower hose (don't tighten down yet!) and do the same with the new coupler at the top going to the throttle body. Adjust the pipe as needed to make sure you have proper clearance of the fan at the bottom and good sealing at the throttle body. Tighten everything down.



Reinstall the electrical connector onto your sensor, lock down the retaining clip to make sure it doesn't come undone, and you're finished!



Start your car, check for leaks or a check engine light, and you should be on your way
