K&N 30-1576 Performance Air Intake System

I installed this today and it took me about an hour. Would have been quicker but I was in and out of the house grabbing tools and coffee.The good...1. Install is easy if you have the right tools and read the instructions, Youtube videos exist so if you need more direction just google Jeep Gladiator K&N Cold Air Intake Install.2. The motor growls when you hit the throttle! I do not want the full sound of an aftermarket exhaust but the stock intake makes no sound at all. If you are looking for a nice growl without being obnoxious (IMO) this is the way to go.3. Throttle response is noticeable better but not sure how much of that is associated with the sound, it could be a Jedi mind trick.4. This is handmade in the USA!1 (according to the box)The bad...1. Other brands do not require you take the grill off and remove the air inlet tube behind. This is not a big deal if you are familiar with removing the grill but it still adds time to the overall install.2. I have had other vehicles with CAIs and sometimes at low rpms they can feel sluggish. Overall they add HP and I believe they are worth it but it is something to keep in mind.I still rate this as 5 stars despite these very small issues.

Installation into a JL jeep was relatively easy, except had to pop off the grille to get the old air tubes out. Installation of this new one is seamless and make the car sound FANTASTIC! Puts a smile on my face every time I hit the accelerator. BUY IT! You will not be disappointed, and don't spend double the money to buy the MOPAR one.

Shipped quickly and was as advertised. Installed myself in about 45 mins. Sleek look and very throaty tuff sound. Love it!

This went right into the 2018 Jeep Rubicon it was designed for. Pretty simple installation, except for one part. The “intake air temperature sensor”, is actually a really fragile part. As long as you pay close attention, you’ll be fine. If you happen to be a forgetful type, put the grommet in when it tells you too, but wait until you’re nearly done to install the sensor.

Made a difference for torque - like the growl- gas mileage improved - when towing the torque was improved a little - really noticeable when not towing for performance and gas mileage

I can't tell you if this helped with anything because I installed beadlock wheels and new 37x13.50r17 tires. But I do like the aggressive tone from under the hood!

All you JT folks don't sleep on this modification, very easy to install, and sounds amazing nice growl for the 3.6

This is probably the 5th KN intake I've purchased in the last 12 years or so. Never an issue with install or performance. They got this one wrong though. Heat index on Saturday was 112 and the engine compartment was hot as well. All went well til the end. 1st, there were missing parts, which they have Fed Exed to me, but the issue has to do with the temp sensor install. I also give 1 star to Jeep because to remove the sensor, you turn it counterclockwise 45 degrees and wiggle it out. Nope, didn't happen. I called KN about the missing parts and also spoke to their tech about the sensor and also looked it up on U tube. Well, I twisted and turned and pulled on it until it broke ( new one is $35 at Advanced Auto parts). I installed the breather tube after receiving a replacement from KN. The major issue is the tube from the box to where it connects to the intake has a hole in it for the sensor to fit in . NO WAY will it work as compared to the OEM tube. Maybe Jeep changed the way the sensor fits the tube that KN doesn't know about. The missing grommet they sent me didn't fit the hole and I had to slice it 3/8 inch to get it to fit the hole and then the sensor still doesn't fit. The hole in the OEM tube is entirely different from the KN tube. Guess I'll just duct tape it until I can figure out something else and stare at my check engine light. Other reviews made no mention of this problem. My guess is Jeep changed the design and if they did, KN needs to come to the dance and figure it out. My Gladiator is a '21. Gonna check with other Jeep owners and look at their intakes, Either way, I'm pissed. At least it's working.

Inmediatamente después de instalarlo se sienten los caballos extras y por supuesto que el sonido que emite está fregón! 👍🏻

I got a big surprise after installing this. It sounds so much better than I thought it would. Great build quality. No drone sounds. As soon as you start pushing the transmission a bit that's when you hear your engine sound completely different. It roars.

Installed it on my gladiator and I love it the sound it adds is awesome and I can definitely feel some performance increases so I very much happy with the product

Easy install, looks cool, small hp gain.

I don’t know whether this product increases power, but it certainly increases induction noise under throttle. Other Jeepers wonder which motor my Wrangler has installed. It may be too much for some people, but if that's a problem then don't buy this product.Actually it is not quite a V8 sound, but an oddly similar uneven note. Very noticeable.Rather than throwing away the OEM Cold Air Intake (which provides cold air under the OEM air box) as per K&N assembly instructions, it is possible to cut the OEM CAI pipe to fit into an added hole cut into the side of the K&N air box. The result is then an actual ram air fed CAI for the K&N air box. See photos for details.
