K&N High-Flow Original Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 2009-2017 Hyundia/KIA: (See Product Description for Select Models), 33-2448

Clocking in 50,000 miles the OEM Engine filter was due for a change so I started looking for replacements and like everyone else we tend to go with what we know. To that end father worked on all of our vehicles growing up in regards to basic maintenance and when able even the much more involved repairs. There have been a few things to stick with me from those days one of which was the awesomeness of K&N filters.After checking the brands with the dealership (OEM 30k mile replacement filter) and a local shop (FRAM 45k mile replacement filter) I started to look online for alternatives which is when I remembered the K&N filters my Dad installed and used for years without another replacement. Finding a fit was easy and the price was comparable to all other competitors yet cheaper through Amazon than retail. Filter arrived with warranty information, info card, and a K&N logo sticker. The warranty information states the filters is reusable and details cleaning instructions, and boasts that you just purchased a Million Mile Engine filter.The OEM filter I pulled out of the filter case was black, like close to pitch black, they were not yankin' my chain last oil change it was time to think about getting a replacement. The K&N was a perfect fit and felt snug when I engaged the clips on the case to make the seal. Now I've been driving with the new filter for the last 5 days and have noticed the following:- Engine idle sounds less rough- Acceleration is smoother through the lower gears- My average mileage via computer gauge shows about 3 mpg improvementAs the subject says I'm impressed but not surprised cause I expected nothing less from a K&N filter. Also there is a info sheet that tells you that using a K&N filter DOES NOT void your manufacturer's warranty which is 100% absolutely true nation wide. So rest easy, spend less money, and get better performance all in one.Oh, I was so impressed the other day I stuck the sticker on the lower left hand corner of my rear window... cause I'd like someone to ask me about it just so I can tell them to go buy a K&N.

i use to by the cost efficient filters for my vehicles and now that they are both (Honda and Hyundai) hitting the 200k mark I decided to invest the engine and oil filters with K&N and it’s a well worth investment. Slight notice in fuel efficiency and throttle response. Easy installation, perfect fit and filter quality is top of the line. Highly recommend especially for diy oil changes.

Before K&N 21.08 41 tank fillsAfter the K&N 22.59 4 tank fills 1-3-12My gas mileage has increased since I installed the K&N filter. I replaced the filter the Santa Fe came with after a year. On my 1994 Toyota Pickup the mileage went up about 1 mpg. To prevent most people from being bored I have the specifics at the bottom of the review.I have used K&N filters since the 1980's and I have never had any problem caused by increased engine wear or component damage. Being a mechanic I maintain my own vehicles. In 2010 I sold my 1994 Toyota Pickup that I had new since 1994 and it had a K&N since 1995. It has over 130,000 miles on it, does not burn oil, and is still running for the third owner with the K&N I purchased back in 1995. My 1996 Honda Civic is still running for the third owner with the K&N I purchased as well. I will not bore you with the rest of my vehicles that used K&N filters. Being parsimonious I thoroughly investigate products and keep my vehicles as long as possible. I get the best parts because of safety and who wants to redo because you use cheap parts?I have tracked the gas mileage on my 2011 Santa Fe since it was new. I got the car December 10, 2010. My average mileage before the K&N filter was 21.08 and the last two fill ups before the K&N I got 19.32 and 19.65 probably due to the winter gas blend. After K&N I got 24.72, 20.48, 21.69, and 23.46.I take the miles driven and divide by the gallons added. To date my average mileage is 21.22 and the mileage calculator the car has is 22.73. The car's calculator is off by 6.64% and it is factory calibrated with gas without ethanol and my 2003 Corolla gets about 7.83 less mileage with ethanol so the car's calculator would be off by 1.19 if I could buy ethanol free gas using this calculation.For my ethanol info read the comment.

I used this on my 13' sonata turbo limited. Dealership wanted 50 bucks to replace filter with a stock paper filter. Seemed like a lot of money to pop 2 clips, take filter out and put new one back in. Installation in this car was a lot easier than in other cars because the filter slots into the box, making the seal and closing of the air box effortless. I guess the tool that puts the filters in at the dealership is pretty expensive lol. This is almost 25-30$ more than the paper filter, but it flows a little more air, and still cheaper than the dealer. There is the 100K warranty thing, but requires services just as often as you'd replace a paper filter which costs about the same as the regular filter (part only, from amazon). Putting the filter in took me quite a while almost 30 minutes. That's only because there were quite a few leaves in the air box that I needed to vacuum, and my shop vac wasn't working so I had to get my house vac. Otherwise it would have been a 10-15 minute affair. As far as performance, and sound, I couldn't really tell any difference. I've used these filters on all my cars and I like the slight performance and mpg boost from them. With other cars that I've put it in, I usually notice a 1 mpg boost which makes me feel like the filter pays for itself. I've only owned the car for a month but I've noticed about the same 1 mpg boost so far.

Perfect fit

Noticed an immediate change in gas mileage, airflow, and my car accelerates so much faster.
