I've heard too many stories about K&N Air Filters not filtering as well as stock filters, passing too much "dirt" into engines. I would not have wanted a K&N when I drove through those four dust storms in April, just West of Flagstaff, on my way to Roswell.
That dust was as thin as talcom powder (red talc) and was everywhere. I trust a stock filter.

BTW, I knew I was probably going to go through dust storms, so I built my own "pre-filter" using the thin home window foam filter stuff. I cut a piece wide enough to fit over the air intakes, just over the radiator, tucked the front under the moulding in front of the intakes, then I sprayed WD-40 on the foam filter stuff. When I got to Roswell, the pre-filter was filthy red, loaded with the red dust, (as was the engine compartment itself), but the engine air filter was in very good condition, with no sign of red dust.
I like this pre-filter so much, I cleaned it, and still use it to this day. Has not hurt the power or the great gas milage.

The K&N Filters work fine provided they are cleaned and oiled properly and at appropriate service intervals. Do they add horsepower? Well maybe 3 or 4 at full open throttle (with a following wind and downhill slope, etc. ) but you won't notice the difference in regular road use. I use one on my 911 that spends a lot of time at the track where full throttle is used a lot more often.
They can also cause more intake noise in some cars which might be annoying to some. I'd agree with crtcbob, stick with the stock filter for road use.

Agreed. I remember changing the filter box for my 1991 Nissan Maxima, thinking I would get some performance benefit. Mostly what I got was a sucking noise like a vacuum and crappier gas mileage. When it comes to oil/air/gas filters I normally default to using the OEM. Would like to hear about other peoples' experience with these aftermarket air filters.

Don't let Hyundai find out about a K&N air filter installed in your car. They would love to get out from under that 10 year drive train warranty.

I put a full K&N air system in my 2006 Dodge Hemi truck that was getting less then desirable gas mileage. It went from 13 mpg to 16mpg and has a noticed increase in acceleration. It is a little louder which is nice for the truck.

I'm going to wait for a cold air kit to be available. More money, more power -not much more power, but i love all the extra room in the engine compartment as well
