K&N High-Flow Original Lifetime Engine Air Filter: Increase Power: Washable: Compatible with 2017-2025 HYUNDIA/KIA: Elantra, I30, Kona, Veloster, Cerato, Forte, ProCeed, Seltos, Soul, Xceed, 33-5050

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.

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!!

2021 Kia Forte LXS (2.0 naturally aspirated) I've had K&N filters before and l love this American company!!! Quality products that work well, perform well and really save the consumer money in the long run. It's literally a no brainer. You have nothing to lose and everything to gain! I didn't but this for performance. I mean, come on, a forte LXS? Just....no........you don't fart can a car like this. It's made for mileage and drama free driving. It's smooth. Those are it's strengths and that's why l love it! This car goes just fine for me. I frequently pull down 48-52 mpg ( ScanGauge 2 equipped, light acceleration, go speed limit ) It's nice to know that this filter will be the LAST one I'll ever buy!!! Less waste in the landfills ( every bit helps ) and no more Chinese made filters for this car!

Easy to open the engine filter cover. Much better quality than the OEM one.

No more buying filters. I have one in every vehicle we have.

Works as advertised.

Actually for those concerned, this filter does fit a 2025 Kia Seltos LX AWD SUV. #33-5050 is what you want to buy. I did the research on K&N's website and found this to be true for the 2.0 L engine. Low and behold, once it was installed it definitely did fit. What you'll notice is not a incredible amount of difference, but at least you'll have the satisfaction of knowing you have a K&N air filter that you don't have to worry about cleaning for thousands of miles. And the little extra added bonus if you're a car guy like me, is a slight drone of air suction from under the engine bay indicating its presence. Anyway, ignore the statement that this filter does not fit the aforementioned vehicle. It absolutely does (Part #33-5050.) If you want to feel a noticeable difference, I'm sure you're going to have to wait for the CAI custom fit kit... OR FABRICATE ONE YOURSELF!

The best filter that you can buy. I've been using K&N for the last 10 years and haven't had any issues as long as you clean up periodically you wouldn't run into any issues just follow the instructions on the cleaning card and make sure when you get your oil changed that the techs don't try to replace it. Make sure you put that warning sticker that it comes with on the filter cover prior to being serviced. Have ran these filters on multiple platforms of vehicles and never had any issues. Will not void the warranty on the vehicle.

Description said was correct for my vehicle evan after putting the reg number in so its turned up and is no use to me at all

Acheté pour mettre dans une I30 1.4 140ch et c'est le jour et la nuit. Avec le filtre papier j'avais un creux en accélérant en 1ère et là quasi plus. Au passage une consommation qui baisse un peu et légèrement plus de couple mais c'est pas un stage 1 non plus 😁. Je recommande

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.

ممتاز جدا سيارتي النترا 2020 1.6 العزم ما تحس بفرق واضح ولكن السياره تحسها مرتاحه بسحب الهوا والاستجابه

Work best in hot and humid weather.
