Good investment. Saw an increase in fuel mileage and performance in my 2012 Hyundai Sonata 2.0t.

I've been using K&N filters since they came out with the open element that I used on my 1985 Regal Turbo. Just like way back then, this filter for a 2.4L GDI engine on a 2013 Kia Optima made it come alive. The improvement in performance is quite noticeable and there is always an improvement in mileage. Those that read this and listen will be glad they did.
