Well I've had the Hennessey CAI on my 2012 and transferred it over to my 2014. (I know its not really a CAI). Anyway - after seeing high IAT temps with the Hennessey consistently 30+ degrees over ambient, I've been searching for another CAI without having to do any modifications like with the BWoody. I landed on ordering the Injen CAI - it's the only one I found that actually has a heat shield. It was shipped in really nice box, packaged well, very good instructions. I am "really" impressed with the design, setup and installation with this CAI. You can tell some engineering went into it versus the Hennessy which is pretty much a big ass filter with metal pipe.
Now the Injen CAI instructions and fitting alignment is for the 2012 and 2013. I did find with the 2014, there were a couple of things I needed to do, so the bolts where the heat shield fit would work. Looks like on the 2014 they took up one of the holes behind the washer tank where one side of the heat shield fits to. It was just a plastic clip holding one of wires for the front headlights. Easy to clip and move out of the way.
Overall impressions - "very impressed". The immediate notice for me was improved throttle response. With the Hennessey and even stock airbox. I always felt like I couldn't quite figure out the right pressure to press the gas from a stop light. Either was pressing it too hard and it would sort of jerk you through the multiple gears or too light and it didn't feel like I was moving as fast as I wanted. For some reason, with this intake; response is instantaneous, the jeep moves forward with ease, pulls at the slightest press of the pedal and shifts very quick into lower gears even in auto mode. I haven't been able to run any comparison 0-60 in best optimal conditions. My best run is usually 4.4 seconds with decent conditions. On the way home, I stopped at my usual spot and ran 4.5 second 0-60 run and it was not optimal conditions today. About 80 degrees on long island and very high humidity. I would bet in better conditions I would definitely see about a 4.3. The IATs are much lower than the Hennessey. Temps were only 10 to 15 degrees above ambient with driving normally. Mid to low 90s with a 78 to 80 degree day. Obviously at stop lights it would climb up a little higher.
Here's some pictures of the intake, tried to capture as many angles as I could. Enjoy and let me know what you think:
