 Very easy installation, noticeably better power and mpg, and a great sound! I love that whistle!
Evan Harris, Wake Forest, North Carolina
 This filter has majorly improved the performance and MPG of my 2012 Hyundai Genesis Coupe. I get an extra 100 miles a tank and I can't thank you enough. I have used K&N air filters on all of my cars including some of my muscule cars that I have built. It's great to know that a company can produce such a great product for cars that is so easy to install and get such great results that even my 10 yr old son can install them. Thank you once again K&N...you're the best!

 The second car I have used K@N's on (33-2958 air filter) and, believe it or not, the already great throttle response has improved with several extra horses to play with plus gas mileage has gone up 3 or 4 mpg which is a real bonus. One other benefit is that the engine sounds better, a slightly deeper throatier tone almost like a V8!
