Just Installed Injen CAI: Thoughts and Pictures

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:

Re: Just Installed Injen CAI: Thoughts and Pictures

Thanks for sharing, that looks pretty awesome! I was thinking of going this route myself and this pretty much solidified my decision. A couple questions:

- Injen vs stock airbox, any notable MPG and intake temperature differences?
- Where did you end up picking up the Injen CAI from?

Re: Just Installed Injen CAI: Thoughts and Pictures

Not enough driving time to notice mpg difference but I will watch this. The stock intake temps were usually 15 to 20 degrees above ambient. I would say that this one is probably right in line with the stock IAT temps; a lot better than the Hennessey. It's probably pulling in more air than the stock at or around the same temps, given the stock intake was enclosed to protect heat and this one has the heat shield.

Forgot to answer your second question. I ordere it online through I believe a site called Hemi Horsepower.

Re: Just Installed Injen CAI: Thoughts and Pictures

don't they offer the aluminum piping like you have and black plastic?


Thanks for the very informative post!

I believe there are two options, the regular aluminum which I have and a black crinkle option. It's not plastic but a black crinkle covering.

Thumbs up Re: Just Installed Injen CAI: Thoughts and Pictures

Looks great and functional. Do you think removing the plastic piece above your driver side headlight will help with airflow? The piece I'm referring to is actually not present on regular WK2 as this is where their stock airboxes get outside air from.

Actually removal or just trimming out a hole to provide more airflow while retaining the structural integrity of the piece and the factory seal...

I'll look at that - I know in the 2014, right in front of that area is where the headlight is, there's also a beam there which holds support for the radiator and where the right side of the heat shield bolts into...

I'm still flat out amazed on how this intake has improved the throttle response. It almost feels like the auto and transmission are in sport mode while still in just auto driving. Must be in their MR technology step down process in the metal piping (it chokes down before it gets to the air flow sensor).

Re: Just Installed Injen CAI: Thoughts and Pictures

I also have this intake and the difference from stock is noticed immediately. I believe the MPG is better by 1-1.5 points but hard to say. I added the Borla Atak at the same time and I find myself stepping on the gas more. Throttle response is way better and down shifts are much more noticable. I would recommend this to CAI to anyone. The best part is that it is much less expensive than the others out there. I bought mine from Fasthemis.com for $232 + shipping.

How well will this hold up to heavy rain, both driving and while parked?
