Review: Fit in 2018 Hyundai Sonata Sport - even though it doesn't have the little side clips/snaps - When first looking the actual product I was concerned that it was the correct filter. The factory installed and OEM filters for the 2018 Hyundai Sonata Sport with 2.4 l 4 cylinder have these two weird little clips that snap the filter snug and in place. This filter does not have these. The filter does come with a frame and some grease that provides a snug and airtight fit. When I say snug I mean it is tight and snug to the point where you really have to push the filter into the cars filter housing box. At first I tried without putting the grease on it to see if it fit and I couldn't quite get it in. Once I put the grease on and pushed extra firmly it went in and fit perfectly and I could see a tiny bit of the grease ooze out the front. I use K&N filters in my cars and have had for over 20 years. This was the most interesting install, but was simply if you follow the included directions. Installation takes about 5 minutes if you have ever taken the factory one out and replaced it. I recommend K&N Air Filters. I feel like they provide a slight extra boost in performance and economy. The big benefit is that when you put the little K&N sticker on the air filter housing the shops stop bugging you to buy a new filter every time you get an oil change. Just a bonus in my book!
Review: Easy installation - My car loves this air filter!

### ⭐⭐⭐⭐⭐ Easy installation
*by R***S on December 20, 2025*

My car loves this air filter!

### ⭐⭐⭐⭐⭐ efficiency and big savings since cleaning and recharging them every +/-40k miles is very easy to do
*by R***. on June 6, 2018*

I've been using k&n filters in all my cars for the longest and they have always given me improved performance, efficiency and big savings since cleaning and recharging them every +/-40k miles is very easy to do. My recent purchase was for my 2016 Hyundai Sonata (Limited w/2.4 L) and the K&N 33-5026 fits perfectly. I don't understand why those purchasing -and giving bad reviews, didn't do their research ahead of time and check its fit in their car. Now I am ready to purchase this model again -also for my wife's new 2017 Sonata Ltd., when it reaches 10k miles to replace the factory air filter.
