Great reusable engine air filter that is very easy to install
This drop in engine air filter is a fantastic upgrade for your vehicle. It fits perfectly into the factory air box and takes only a few minutes to install with no special tools needed. The build quality is very strong and durable since it is designed to be washed and reused instead of thrown away. It helps your engine breathe much better and provides a nice steady performance. It is a wonderful investment that saves you money on replacement filters over the lifespan of your car.

Great fit and washable
First and foremost, the fit was absolutely perfect. It matched the specifications of my car exactly and installed without any issues. The design and quality of the filter are top-notch, and it felt very secure once in place. One of the best features of this filter is that it is washable and reusable. This means that instead of having to replace the air filter regularly, I can simply clean it and put it back in. This will save me a significant amount of money over the life of my vehicle, making it a cost-effective and environmentally friendly option. The performance improvement was noticeable immediately. My engine runs smoother, and there’s a slight improvement in acceleration and overall efficiency. The high airflow design ensures that the engine is getting the optimal amount of air, which is great for performance and fuel economy.

Great alternative to throw away air filters!
Bought for my 2020 elsntra sport, great alternative to replacing my stock air filter every three months. I did notice a smoother idle and a tad more throttle response. You will definitely see the fuel performance if you’re doing highway driving not so much around town overall very happy with my purchase.

Worth buying
Wanted to get a little more horsepower out of my vehicle. After investigating ways to achieve that, there are really not a lot of options. I have been using K&N filters pretty much on every car I have purchased, so I bought one for this vehicle. I love that it is washable and has a great warranty. So if you're looking for an inexpensive way to gain some HP, I definitely recommend this

Worth the price of a smoother running engine.
I always use K&N filters. I have the cabin filter and of course the engine air filter. I like knowing I'm doing something to help my engine work efficiently as possible and K&N helps me do that.

Super easy to install on 2018 Hyundai Elantra Value Package and already seeing perfomance improvement.
I've had K&N Filters before on my full size pickups and thought they were really great. Just installed on my 2018 Hyundai Elantra Value Package. First of I have to say that the Elantra is not a race car. It's a nice small economical car that will consistently deliver 33-35 mpg mixed city and highway driving. That being said, it has always driven me nuts that it is a bit slow off the line. I'm not expecting much so no big deal. Just installed the K&N air filter and it has already improved the initial take off slightly. It doesn't feel as sluggish or resistant to taking off. I don't expect it to be fast or quick, but I do like the general improvement this filter provided. I keep a close eye on my fuel economy and look forward to seeing if this gives an extra mile or two per gallon. It is super easy to install and comes pre-oiled. In the future when I clean it I will need to purchase the K&N Oil and cleaner for it, but I have many miles to put before I even have to think of it. Overall, I highly recommend. This is a huge improvement over the factory filter. You pay more for it up front than you would a regular filter, but I think it is well worth it.

Simply the BEST filter for your car
I work in the automotive aftermarket and was a K&N distributor prior to their consolidation to just a few master distributors about a year ago. We had what was called a "demonstrator" whereby you had a clear acrylic air box with a 2 foot tube that went straight up from the box. Inside this tube was a ping pong ball that when turned on, would "float" at the very top of that tube. The way it worked was you could add "any" brand of paper filter to the hole in the airbox and the ping pong ball would drop to the bottom of the tube due to air restriction. You would then remove the paper filter and the ping pong ball would shoot back up to the top of the tube. We would then add the K&N filter to the same hole and there would be ZERO change whereby demonstrating the massive difference in air flow. What this simply means is your engine gets more air. More air translates to increased HP and better fuel efficiency. K&N uses surgical cotton in their filters whereas any paper filter has interlocking fibers that end up restricting the air. Additionally, it has a million mile warranty! If you add up the cost of regular filters used when you get your oil changed, although the K&N has a higher cost up front, you save potentially hundreds of dollars depending on how many time you get the oil changed and how long you hold onto your car. I'm going on 16 years in one of my vehicles. So if you're on the ledge, really it's a no brainer due to better gas mileage, increased HP, and never having to buy another filter as long as you own your car. HIGHLY RECOMMEND!!

Parfaitement adapté à la KIA PROCEED GT 2019 1.6 T-GDI
Qualité du filtre K&N habituelle, installé en moins de 2 minutes, 2 clips a retirer et remplacement du filtre papier d'origine. Il est parfaitement adapté à la boite à air même dimensions que celui d'origine. Premier tour de roues avec le nouveau filtre pas de changement niveau bruit, un ralenti légèrement plus haut et une accélération plus ronde. Si il est nettoyé tous les 15 000 kms le filtre peut largement tenir plus de 100 000 kms. Très satisfait de mon achat et du prix.

Goede K&N inlegfilter (Kia Xceed en Proceed)
Goede vervanger voor de luchtfilter van de Kia Xceed 2023 en de Kia Proceed 2022. Pasform is perfect

Better Airflow and Improved Fuel Consumption
Love these filters. Car goes so much better with this installed and is more responsive. Fuel consumption is better noticed on the last 2 tanks of fuel. Any fuel saving is a bonus. I have a performance vehicle anyway but the pick up and acceleration is better with this filter. Then to top it all I never have to replace the Air filter again as this one will last and is cleanable. Would highly recomend anyone to buy one yhey are not much more than a standard filter but so much better.

Passt auch beim I30 N-Line 1,5l 48V Bj. 2022
Das Produkt ist in typischer K&N Qualität. Passt auch bei meinem I30 N-Line von 2022 (11.02) 1,5l 48V Hatte bei K&N auf der Webseite nach den Daten geschaut (Abmessungen) K&N 33-5050 und diese haben dann mit diesem Produkt übereinstimmt. Darauf hin habe ich es auf gut Glück gekauft und hat Perfekt gepasst. Leistung: Mehr Turbo Sound und besseres ansprechverhalten, ob er auch mehr Leistung macht müsste man genau testen, fühlt sich aber im allgemeinen besser beim Beschleunigen an. Preis ist hier auf Amazon am ist am niedrigsten und Versand war wie gewohnt 1 Tag.
