Recently, I replaced my stock-paper air filter with a K & N air filter.  The vehicle is a 2002 Kia Sedona, 3.5L with 105k miles.  '02 was the first model year for the Sedona and was notorious for poor fuel economy - possibly some design flaw (which I believe is in the airflow/fuel mixture-with the paper filters being too restrictive).  Since I installed the 33-2268 I have been monitoring my fuel economy regularly.  Now, with the sixth full tank of fuel run through it-my mpg has increased an average of 7-10 mpg, depending how the van is driven (highway to city driving)!!!!  In these tough economic times, every mpg and dollar saved counts!  Thanks K & N.

We purchased our 2002 Kia Sedona van from a friend who no longer needed such a large vehicle. He always stated that it only achieved no better than 21mpg on the highway. Well, the first thing I did was to find a K&N filter on the web and get one for this van. In town mileage improved somewhat but after changing the oil with synthetic and having the plugs changed, mileage really improved. We just returned from a 1600 mile Texas vacation and got a high of 24.4mpg at an average of 70mph! To clarify things a bit more, our friend mostly traveled alone and this trip to Texas was just my wife and I; although we did bring back lots of souvenirs, gifts and Christmas presents. I didn't check the mileage on the trip home because I know the added weight of "stuff" helped drop it. I'm just glad to know that the mpg has gone up period. I also like the growl it makes when I accelerate hard.

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.
