Been using these the last 20 years and they are still a quality product. When the factory air filter needed changing on my new trucks I always replace them with a K&N. I don't know about power increase but I did get 2 mpg increase on my 2014 F250 Diesel. Better than buying a factory filter every 15K miles. My 2006 F150 got over 100K before I had to get another K&N for it and it's still running good.
