Easy quick install for me with the Perrin charge pipe also definitely made a difference on the temps.
Bought this intercooler based on some good reviews and the decent price. This was the worst install I have ever tackeled on my car. The hose clamps and hose provided are garbage. I had the hose and hose clamps on the throttle body side blow off 4 different times when I test drove it after getting into any sort of boost. I even tried T clamps which others recommended with this install, still no luck, blew off again. I tried the clamp the hose down so many times that the hose part is already wearing down to the center material. Overall extremely dissapointed in this product given their strong reputation with the verticooler they sell. Spend the extra money and buy the grimmspeed unit, don’t cheap out like me and make the same mistakes.
A big plus was able to get temps down in this desert heat. Really enjoy the looks of as it sits there. Intake manifold is painful. With the 2018 but once you get it your good
Now let me put it out there that I'm extremely happy with this intercooler. The cooling is great, it looks great and fitment is great. Now the only thing that was a pain was getting the coupler onto the throttle body and the intercooler. Seemed like the coupler was too small so you really have to work it onto the intercooler. Other than that it's awesome. Also this car has alot of sharp objects in the engine bay. Wear gloves, I didnt and it looked like I ran my hands in the garbage disposal.
Overall I was impressed with the quality of the intercooler. Looks great under the hood ,fit perfectly with the perrin charge pipe. It also came with an alternator cover which is a plus. The only issue is that there seems to be a design change in 2018 so the provided splitter does not fit properly without some minor drilling so just a heads up if you have a 2018
