Added K&N Intake to 2012 3.6

After finding a crack in my factory intake pipe I decided to install a full K&N intake on my 2012 3.6. Install took me about 45 minutes and was very straight forward. Fitment was excellent and extremely sturdy. The only part I didn't use was the factory scoop from under the hood (my HID box is installed right there with a bracket that prevents me from using the factory scoop).

I love the sound of the engine now. A low, but noticeable growl at low rpms and on the highway, and a very nice growl once I step on the throttle.

It's only been installed for 2 days so I can't comment on mpg just yet, but I will report back after a few tanks to see if there's any difference.

I have a tune on the Jeep from Sean at hemifever. The cracked intake was causing some hesitation and stalling issues. Now with the new intake paired with the tune, the Jeep feels amazing. Very happy with this purchase

Looks great! People complain about intakes claiming they aren't worth the money, but for me that growl is worth it by itself.

Sweet. If I ever get a crack on my air filter I will get a K&N CAI as well.

Bake, in your opinion, do you feel any acceleration gains? Does it feel faster? I know the sound may make seem faster but I am curious to see if it is indeed faster.

I also have a Hemifever tune. Currently running the 91 octane. With 32 inch tires and driving very moderate I'm getting between 18.5 to 19 MPGs.

I ordered a Spectre CAI and a AEM Dryflow cone filter to adapt to the Spectre as I don't like oiled filters.

Not long ago, I owned a BMW Z4 2.5 inline 6. I installed a AFE Intake and I immediately noticed the power increase. The car felt faster and it was faster. I confirmed the acceleration times with Dynolocious and G-Tech and it was a 1/2 second faster to 60 MPH.

Re: Added K&N Intake to 2012 3.6

I just put a spectre intake on mine today. Make sure they send you have the throttle body coupler/reducer when you get it. Mine was missing and while customer service fixed me up, I have to rig it on with a rubber piece from Lowes.

Without a dyno before and after an intake, it's hard to tell whether or not it's faster. I like to think it is though

I don't think I noticed any difference in power or throttle response. Just sound. But I also have a very heavy stereo system in the car as well and every panel is sound-deadened so the thing is a tank. my MPG went up which is the best and most noticeable gain.

Re: Added K&N Intake to 2012 3.6

I took off my Spectre a few days after I installed it. The sound was just too loud for what was really not much happening in acceleration. My Jeep was actually a second or more slower to 60 MPH when compared to the stock box with an AEM drop in filter. I read a good explanation as to why your gas mileage increased.


Apparently under normal driving condition other than WOT, with a CAI (more like HAI, hot air intake) your car is sucking much warmer air (I measured the intake temps) (which is less dense) requiring less fuel. It was a long article that explained this but the essence is that the hotter the air coming in, the less fuel is required given the density of the air. That does not translate to using less fuel and generating the same or more horsepower at the same RPMs as pre-CAI (stock box). We are comparing same RPM level/trans gears. You would need to drive at higher RPM to generate the same power as the stock box which would erase any gains in MPGs.


Just my 2 cents.
