Rev9 Intercooler for 2016+ Honda Civic 1.5T.

I will be installing this is my 2018 Honda Civic SI.
I wanted an upgrade solution over the factory intercooler, while keeping factory intercooler piping and looks. (Sleeper)
Living on the central coast I saw some ridiculous IAT temps last summer.

After hearing from a few users using this intercooler with good results but not much info out there I decided to make the purchase.

Here is what $300 gets you.
Overall quality and appearance looks great. Arrived well packaged with no bent fins or dents. Welds look suffice. The end cap castings look to be of good quality and are nicely deburred. It does appear to be aluminized painted. There are a few runs but no big deal.

Update: Install:

Install went smooth. Remove the front bumper. This video is a great guide.
After the bumper is removed it's as simple as remove the hold down mounts on each side. Remove the intercooler piping. Rotate the intercooler forward and out. Installation in reverse. Everything mounted well. I did have to trim some of the plastic shrouding as the intercooler is larger.

Unfortunately my data did not turn out. However I can say that I drove the car and got some temperature into it. I then made four 2nd and 3rd gear wide open throttle pulls. I then turned around and made four 3rd gear wide open throttle pulls. I finished this up with some start and stop traffic. Ambient temperature was 65 degrees temperature post intercooler never exceeded 85 degrees during any of this testing. For the price I'm happy with those results.
I will be doing some autox the next following weekends and will see how the improvement is there.

i have been using this intercooler since 3 months, did some datalogging on flashpro and IAT has been stable around 10-12c over ambient temp.

How is this holding up? also are you using stock piping or another kind?
Not certain that REV9 is incorporated with Agency Power, but it looks very much like their product.
It has a “high wall” front with 3 addt’l rows and is “step laddered. No fins to direct the airflow. So, the air stream will be bouncing all around inside.
It uses stock tubing.
The one advantage that the unit has is that it is Bar & Plate vs the Stock Tube & Fin.

In 65deg ambient the stock IC would keep IAT2 at the same level as this model under boost. IAT is not controlled by an IC, only IAT2.

I upper 3 rows of intercooling is interesting. It has 11 rows of fins vs 8 that I have seen on some intercoolers.
