From research I've done nothing really adds that much performance. All false hope. You gotta void the warranty to get any real gains. You might get a little from opening up the airflow but you won't get much as far as actual felt difference. Good luck

None of that stuff works on a JL right now. And when they do, none of it will improve the performance of your Wrangler in a true, measurable sense. The Wrangler's performance attributes are off-roading, not on-roading. So, if you want the best performance for it, buy it a quality lift kit, regear it, and slap on some big ass tires.

And please, for the love of everything sacred and holy in this world, don't put a CAI in your Wrangler. If you want to burn through a few hundred bucks, just take some cash out of your pocket and literally light it in fire. When people ask what you're doing, you can tell them you're using your CAI.

Supercharging is probably your best bet but will void the warranty

Long ago i took my first wife shopping, she loves yankee candle. She always ended up in there and spent a fortune. I always told her to just light my damn money on fire it’s the same damn thing. She always replied that it smelled good and made her happy.


What do you know, she was right..... I did feel more relaxed when I found a scent I liked.

Performance is not always about what you do to the engine. Take as much weight off as possible and you'll see improvements in acceleration, handling and braking. Go for lightweight wheels.

Contrary to forum wisdom, mods you do to your ride wouldn't void warranty unless the mod caused a problem in the first place. But check your local laws.

Please explain. Serious, no snark. I’m coming from the import world where a CAI has mixed results based on many factors. Sometimes a waste of money, sometimes useful depending on other modifications done to the power train, ECU, and exhaust. So why useless on the Jeep?

They do nothing except sound obnoxious. The 3.6 is optimized and short of putting forced induction on it, you are not going to improve it's performance, and in fact, like with aftermarket exhausts (which all have a negative impact on performance), you will likely have the opposite effect.

Optimized for what? I’d think every engine could benefit at least a little from a high flow intake and exhaust.

God forbid if someone wants to do something with their own money like modifying a Jeep to their liking :D Even the stock JL itself is obnoxious with its side vents and pretend hood vents... not to mention colors like Hella Yella... you should ask FCA to release colors named like daffodil, parchment, healthy prostate, etc.

Benefit yes but noticeable? Not without measuring equipment or under artificial/unlikely conditions. The sound is great though... worth it just for the sound.

Why does divorce cost so much????


It is worth it!!!

Any benefit is miniscule and only measurable on a dyno. The increased in-cabin engine noise you'll hear may make you think you feel a gain, but it's an illusion. Been there, done that.

I've had one vehicle where a CAI and a "chip" made a big difference, but it was an F-250 with a 7.0L turbodiesel. I put a CAI in a 3.6L Pentastar-powered Charger. That was a waste of good beer money.
