2012+ Performance Upgrades

Just curious if there is anything out there to look at in terms up upgrading performance on the new engine placed in the 2012's and 13s.

I've read that they haven't cracked the software for tunes yet, but was wondering what else I could do to improve performance. CAI seems to make a nastier noise which is nice, but not much more in terms of HP. Correct?

Any insight would be greatly appreciated. New on the forum and just trying to learn a thing or two.

Thanks!

this Amazon.com: aFe 75-12092 Stage 2 Pro-Guard 7 Air Intake System for Jeep Wrangler V6-3.6L: Automotive
adds about 6+ Hp to the rear wheels on the dyno. Not half bad for less than $300

have you seen any improvement to your mileage after adding the intake system? just wondering. i've looked at them before but wondered if the extra claimed horsepower was really noticeable in some measurable output....other than a dyno.

To the OP, I'd just hold out. An intake/exhaust upgrade won't really show much result without having the tune to adjust fuel/timing curves to match the new airflow.

It already has almost 300hp and even on 35s with stock gears and a slew of added weight in armor, I can still roast an occasional Mustang.

It's only 6 HP at the wheels but I'm doing the AFE intake anyway just to hopefully get some better throttle response. The problem with the 3.6L is that it doesn't make it's peak horsepower until the engine is screaming near redline. In the 2,000-4,500 RPM range it's barely making more power than the old 3.8L. So that's why so many people are disappointed.

This engine makes more HP than torque...it was clearly designed for cars and crossovers and they just adapted it to the Wrangler/Ram to save production costs, but in an ideal world it's not the #1 choice for a 4x4.

I've seen plenty in the past week alone. One guy yesterday even called it a "dog" with his 1,500 lb. trailer on it.

I'm just sayin'.. the reason why it's not as impressive in life as it is on paper is because you don't get that 82 extra horses until you're way past the point in the powerband where people like to be.

That's interesting. I'm still on stock gears and have zero problems with power. Maybe he's running 35+ with stock gears, which could be a dog in any vehicle with nearly a ton behind it.

My 2012 is considerably faster and better offroad than my 2010 was. Not sure what people are complaining about.

I'd say wait till tuners come out. A lot more potential to be had with this motor.

I'm not disappointed, plenty of power. I use my Super Duty to pull trailers.

Drive the motor like it suppose to be driven and it is fantastic. Nothing wrong with getting into the power band. Drive like an old lady and you will be disappointed.

6hp is at 5000rpm's, it is more like 1 to 2hp at normal driving rpm range. Not a lot for $300 dollars

QFT!

I bought a Jeep for off-road use and summer fun. It's not purposed or designed for towing a trailer, even though it can. I bought a truck for towing/hauling.

I don't know why some people are so down on Cold Air Intakes' and Throttle Body Spacers.

I installed a aFe Power Stage 2 Air Intake w/ standard dry filter and a aFe Power Silver Bullet Throttle Body Spacer in my 2012 (3.73 gear ratio). First I installed the CAI. Noticed a difference. Then installed the spacer 2 weeks later and noticed a difference above that.

Better low end power and acceleration. If you add up what is says on the boxes it should be an additional 18hp and 27lbs x ft. torque. Probably not but I would bet it's at least 10hp and 20lbs x ft torque.

I am very happy with my investment (about $400 for both). The 3.6L Pentastar is good but it needed alittle extra oomph. Which I got. Plus the v8 sounding humm is nice too. I have heard that adding a CAI if more effective than adding a CAT back exhaust for power.

Besides a chip the only other options I know for adding power are a Supercharger (about 7k installed) or a HEMI engine swap (15K to 20K installed).

I am very happy with my 2012 w/3.73's. I tow my 3400lb boat with no problems. Of course my 5.7L Tundra pulls like it's not there but it is not a Jeep. "Tows like a dog" and other such statements are always subjective. If the comparison is against a 2500 pick up truck or the like I can see it as true. Compared to my 2005 TJ Unlimited the JK tows like a dream.

CAI's can only may make power at WOT so for me it is a complete waste of $ especially for 6hp at the top. I rarely if ever drive that way.
You cant add the power claims from the boxes of bolt on's. If that were the case there would be 300 hp 4.0L's all over the place. BTW... why are they called cold air intakes if they collect air from a heated engine compartment?
