I have a 2014 Trailhawk V.6 and I have only just started adding parts. So far I have only added the K&N cold air intake, and I would really appreciate advice to increase power (only partially for offroading).
I apologize if this post is in the wrong section--
There is a plenum upgrade as well. As far as tuners, I've never seen a valid probable claim towards them. Headers aren't possible, last I checked however you can do an exhaust upgrade as well but it may screw with ground clearance.
Len, Actually an exhaust (Magnaflow in my case) will save your room and weight, the only thing you have to watch out for is that you may lose a little bit of departure angle depending on how you setup the exhaust tips. Plus it picked me up about 5-7hp according the Torque app (multiple runs before and after) and sounds much better. I am interested in the plenum upgrade you mentioned, is this a manifold plenum or just a replacement for the stock intake tube (something already replaced with other intake kits)?
I've seen some aftermarket exhausts drop lower between the rear lower control arms and I knew about the exhaust tips lol. Since the OP has a KN kit he didn't get the intake plenum that something like AFE comes with. It's about 100$ or so but they do make one, I've seen it. I'm not apart of the Facebook group that posted one anymore so I can't say where it is.
I have the aFe CAI, so what are you talking about: intake plenum? My kit does replace the silencer air box, if this is what you are referring to. After installing this kit, the throttle response is awesome. I actually spun the front tires yesterday, taking off from a stop light on a slick road.
My understanding is that the KN doesn't go all the way to the intake and some factory parts are reused. The AFE one doesn't and has a smooth tubing system all the way to the intake. I could be calling it something wrong. It's a piece of tube the KN kit doesn't come with but the AFE does.
Not trying to hijack the post but I have a 2016 jeep Cherokee limited with a 4 cylinder this is in serous need of a HP upgrade. I can not find a air box upgrade for the 4 cylinder has anyone found and installed one. Any info would be appreciated.
Thanks for the quick reply the turbo option was looked at but this is not an option because of the cost. I have found that K&N makes an air intake now -
77 Series Air Intake
Free-flowing Aluminum Tube
Silver Powder Coated Finish Intake Tube
Not legal for sale or use in California
77-1570KS
Has anyone tried this air intake if so how loud is it in the cabin.
I am also lookin at the MagnaFlow Exhaust Products 15293 MF Series Performance Cat-Back Exhaust System , Is there anyone that has installed this exhaust system.
I too am debating on the KN on my 4. I have not seen any posts where anyone has actually put it on. One of us has to be the test case soon. I'll prob bite the bullet in next month and get it.
Let me know I am looking at the biting the bullet on the MagnaFlow system first and just get a K&N Air filter until I have the extra cash to do the CIF
I really love the growl of the stock exhaust system and hope more aftermarket ones come out that will be affordable. Headers would be nice, too. Why? Why not! >
Headers would be great, however, unfortunately the exhaust manifolds are cast onto the heads so you cant just replace them. What we would actually need is someone to develop heads and headers, which would give us great performance gains but also come at a very significant cost. So finding someone to do the r&d and then manufacture them for the maybe couple hundred people who would actually install them is pretty unlikely (unless there is enough similarity/interchangeability with the 3.6 parts to make it worth their while)
I've had the aFe CAI on my V6 for about 14 months. I like the grunts it makes when I need to jam the gas, but rarely do I need to do this. Usually it's not bad at all in regular use but I do get that extra bit of power when needed. I haven't seen it effect my mpg either. At least on the highway. I've been able to hit that magic 28 a few times when I haven't had headwinds or crosswinds.
I was lucky enough to find one here in the classifieds. I looked at the K&N too. I liked that aFe basically used the stick airbox with an open top.
Whether actually measurable on dynos or not you can feel a change in power. Good product. I use the dry element with 2nd stage cover as well.
It is much better, I can really notice when going 30-40 and need to accelerate quickly, it actually jumps now where before it dogged for a few seconds then caught up. Its still a 3500lb Jeep being pulled by a 2.4 but overall I am happy.
Next project is the opposite end of the intake. Maybe this should go in a departure angle or rear bumper or exhaust thread ?
1. Remove OE muffler and piping back to catalytic converter.
2. Remove rear fascia below hitch.
3. Install new rear bumper.
4. Install MagnaFlow Exhaust #10416 after catalytic converter with creative piping (maybe up and over instead of down and under cross member)
5. Reuse existing hanger hardware
6. Maybe add skid plate between gas tanks and on rear PTU.
End result is a clean rear end with a performance exhaust and maybe a little growl. See photos.
That sounds pretty expensive but I like it. I would do a slight lift before that, but that's me. The TH already sits at a decent enough height for me though so maybe this would be a fun project. I don't like the stock muffler on the V6 TH. It's huge.
How much welding is involved?
From friends with different vehicles, they sure love their Magnaflow exhausts. They do sound nice. Of course since not Track Hawk exists yet putting in a better intake and exhaust are about the only real options for any performance tweaks. They probably don't add much but allowing the V6 to breath better at both ends is nice, though as with motorcycles the post catalytic options are more about the sounds and the looks.
Too bad you can't put headers on the engine. In states where emissions aren't checked annually that would make for a lot of improvement but FCA made the V6 so headers an not be installed.
Because of the high snow/salt Winters this isn't an option for me.
With the Compass TH out and looking as something I wouldn't buy, but I could see others buying, these are things they could do to improve the I-4s performance. Their 0-60 is 9.4 seconds. Horrible for entering freeways.
So I see a few peeps with one or the other aFe or KN. Has anyone come to find one better that other? I'm looking to do a CAI on my 2.4L but didn't know what would be best option based on previous posts...Also didn't see the aFe part listed for 2.4L.
I just put a K&N in my 2.4. It's pretty loud above 4 thousand rpms. Not sure if I like it. Gonna check to make sure it's all in correctly but if that's how it is I'm surprised it's that loud.
Any advice about noise level above 4 rpms?
