Review on 🔍 K&N Engine Air Filter: High Performance, Washable, Replacement Filter: Compatible with Hyundai/Kia 2009-2017 Models (Azera/i45/Sonata Hybrid/Sonata/ix35/Santa Fe/K7/K5/Optima/Sorento/Sportage R) 33-2448 by Nate Nelson

I used this on my 13" Turbo Limited Sonata. The dealer wanted $50 to replace the filter with a standard paper filter. Seems a lot of money to be to fit 2 clips take out the filter and put a new one in. Installation on this car was much easier than other cars as the filter goes in the box making a seal and the airbox closes.bright.I think , the tool that installs the filters at the dealer is pretty expensive lol That's almost $25-$30 more than a paper filter but it lets in a bit more air and it's still cheaper than the dealer There is one $100,000 warranty, but requires maintenance as often as replacing a paper filter, which costs about the same as a regular filter (part only, from Amazon).Installation d es Filters took quite a long time, almost 30 minutes. This is only because there were quite a few leaves in the airbox that I needed to vacuum out and my store vacuum wasn't working so I had to get a home vacuum. Otherwise it would be a 10-15 minute romance. In terms of performance and sound, I didn't notice any difference. I have used these filters on all my vehicles and love their low performance and increased fuel consumption per gallon. On other cars I've put it in I typically see a 1mpg increase which makes me feel the filter is paying off. I've only had the car a month, but so far I've noticed about the same 1mpg increase.
