Kris De Brouwer, Belgium
After reading reviews, I decided to go for this filter instead of the stock one....immediately I noticed better gas response, better fuel mileage (have driven about 300 km since installing) and an overall much more enjoyable experience. As this was the first time I changed the air filter (installation is easy, even for someone with 2 left hands like me - took me about 20 mins) I cannot compare with a brand new stock filter, but considering the difference in materials and technology, my experience would still stand.
