Best addition to any vehicle!
This is the first modification I make on all my vehicles. I can feel the change in the engine response after installing the filter. Power has increased, fuel mileage has improved and driveability is better than ever. This is so easy to install and the price can't be best. You can't go wrong installing a K&N filter.

Incredible & Seamless Install, Precise Fitted Filter
Incredible product and measured fitting. This has been one of my smartest purchases and have saved myself filter replacement 100 times over. I highly recommend purchasing K&N filter cleaning kit to maintain the filter longevity.

First mod every time. If it has an engine, it gets a K&N.
I’ve dropped a K&N air filter into every vehicle I’ve owned—cars, trucks, Jeeps—you name it. Why? Because it’s the easiest upgrade with the longest payoff. No more buying throwaway paper filters every oil change. Just clean it, oil it, and keep rolling. ✅ What I Like: Lifetime filter – One-time buy. Pays for itself fast if you keep your rigs long-term. Better airflow – Every engine I’ve installed one in felt a little snappier, especially under load or throttle. Reusable – Clean it every 50K-ish miles (or sooner in dusty areas), and it’s like new. Direct fit – Drops in like a factory filter. No mods, no headaches. ⚠️ What Could Be Better: Cleaning/oiling is messy – Be ready for gloves, towels, and a little patience. Not for everyone – If you never want to touch your air filter, just stick with paper. Costs more up front – But long-term? You’ll be saving big. 🔧 Pro Tip: Pair it with the K&N recharge kit and mark your mileage when you install. That way, you’ll know when it’s time for a clean—not a guess. ⭐ Final Verdict: This is my go-to upgrade—reliable, effective, and cost-saving over the life of the vehicle. If you like simple mods that actually do something, this is it. I don’t even think twice—I just buy one for every ride and call it a day.

Surprising improvement. And an honest must have for a JK. GET IT
I've used K&N filters for the last 20 years. Mainly because I can clean it instead of replace. I had a drop in put in my Jetta, and while it's not like it added 50hp, it helped with throttle response, but nothing as noticeable as the one I put in my Jeep. It's like a different engine. It's like the 3.6 can breathe for the first time. Acceleration is VERY smooth from a stop, without the bucking and bogging down of the stock style filter. It pulls harder, requires much less throttle input, and with a stick shift, hauls a$$ like a scolded dog if you get on it. I've always liked the brand, but this is the first application where the hype isn't hype. So watching to see if the gas milage improves as much as others report.

Reliable, Reusable, Good buy
For those who don't know- these filters come pre-oiled. I made the mistake of oiling one for my motorcycle and it sucked some in the MAF sensor. After drying it in the sun and wind for a few days no problems. I want to say my MPG and performance increased but it could be just in my head. The biggest thing for me with K&N filters is they can be cleaned and reused. Simple, easy. For any off-road vehicle, I would suggest buying two. That way you always have one if you need to change it out on the trail or one to run while cleaning and re-oiling the other. I prefer the drop in as opposed to the CAI (cold air intake) dust? mud? water?

I bought this for new Jeep Wrangler 14 and it does not fit correctly as small gap which prevents it sealing I used black tape to make the seal and it's on needs to be modified.

Ist halt nur ohne Reiniger und Öl. Aber das braucht man ja erst bei der nächsten Inspektion.
