I ordered this filter on Wednesday morning 22-01-2014 and it arrived at 11.am Thursday 23-01-2014. Fantastic service. Half an hour later it was installed, I then went for a drive through the town and saw an immediate 50 percent improvement> Then drove out of town on 40 mph roads. The performance increased by another 35 percent approx. I am now getting an average 32 mpg around town. My car is a 2005 Ford Focus C-max 1.6 petrol which was giving poor mpg. Your filter is excellent Thank you.

So far so good. I have had this filter on for about 17,500 miles now. I have yet to clean it... just took it out the other day and knocked some large leaf pieces out of it. Filter over all is still very clean. When I had my HEMI Ram and Challenger I was cleaning the K&N filters every 10,000 to 15,000 miles, and they would be almost black. I do lots of driving (about 60 to 70 miles a day for work) and I'm glad with the smaller motor I don't need to clean it as often. This filter helped me get my best MPG so far (41.3 MPG) and before the filter the best I could get it up to was about 37MPG. I bought the Mazda to save money and to commute to work. The K&N is definitely helping with the saving money part. The first thing I do after buying a new car is find out if there is a K&N filter for it. Keep up the good work.
