Great filters I use them on all of my vehicles, especially my 2010 Hyundai Tucson: The filter is tucked up thru an access hole in the skid plate, and is hard to remove using a common filter wrench. Love the removal nut I even use one on my 1988 Harley-Davidson 1200 Sportster. I just wish the were a little less expensive.

Fantastic CAI! Throttle response is much improved, the sound this thing makes is great and very easy install, about 30 minutes. I would absolutely recommend this product . I put it on a 2016 hyundai elantra sport 2.0 engine.

I'm a lady and doubt anything the 1st mechanic tells me just to make sure I'm not being ripped off. So, during my oil change he asked me if I wanted to replace the air fitler? I thought it was included as they incl. it at dealership for same service. So, I told him no despite the leaves and crap in it. lol I googled it when I got home and realized it really does need to be replaced for the functionality and better performance of my Hyundai Elantra GT 2013. Came across this site and great reviews on YouTube on same vehicle, so I made the investment. I cannot explain to you how it feels like I have a new sports car. The difference is astounding My car accelerates fast and just goes faster period. It is like night and day.I found myself racing Hondas and BMW's now. Haha. Hondas I past now, but not the bmw unfortunately, but I give them a challenge make them double take my car now. I also got about 40 more mile out of a tank of gas may have gone further as I didn't run out before refill. Proof was on my fuel stop app. Worth the investment. Thanks
