"I have had K & N filters previously. In fact I have had one on my 2000 Chrysler M since the beginning and love not having to buy and install new filters very often. With the cleaner kit I have, I plan on using the new filter for a very long time. It fit perfectly in the place it was meant for. I really haven't determing if there is an increase in HP or mileage. I beleive the specs did not show a big improvement. I was more interested in the longevity factor. I hope you make one for my new GMC terrain I am buying with the V-6 engine." —Harvey K from Farmington Hills, MI bought a K&N Air Filters for a 2009 Hyundai Genesis, 4.6L V8.
"The cost of a K&N filter and performance increase is the only way to go.Long term saves you money over disposable air filters and increases performance and better gas mileage." —Bruce P from Mcdonough, GA bought a K&N Air Filters for a 2009 Hyundai Genesis, Sedan, 3.8L V6.
"This replaced the original filter which was surprisingly dirty after only 8k. I can tell the engine responds more quickly and fells like it has a little more torque. I'm also saving approx. 1.5miles/gallon hwy and approx. .8miles/gallon city. When you figure that it has a lifetime guarantee and you only clean it every 50k, it's really worth it. I just wish they came up with a cold air intake for it too - I have one on my Focus ST and it makes a big difference in power, torque and exhaust sound. I love K&N !" —Codrut D from Parma, OH bought a K&N Air Filters for a 2009 Hyundai Genesis, 3.8L V6.
"though I was hoping for better gas mile-per-gallon, I am satisfied because just as I read on an earlier review the car does not hesitate from a stop anymore." —James F from Rowland Heights, CA bought a K&N Air Filters for a 2009 Hyundai Genesis, 4.6L V8.
"I just replaced oem to K&N air filter. I don't really feel the difference in performance but it fixed the hesitation is gone at low speed." —Joshua Y from Fremont, CA bought a K&N Air Filters for a 2009 Hyundai Genesis, 4.6L V8.
