Well I have been using K&N panel air filters for many years. I am a taxi in Cambridge, done 449,000 miles on a Mondeo diesel estate, 340,000 on a audi A6 diesel estate. Now just got a Toyota Avensis 2.0 diesel estate 10,000 miles, all these miles on above cars I had from day one a K&N air filters. Yes as soon as you fit air filter you notice the difference in slight more power, smoother, its a no brainer to buy and fit. Work it out about every 40,000 miles need to buy cleaner and clean the filter not because its noticeable driving car but it just looks dirty, every service you do not buy a air filter. Only a few services and you got your money back on the cost of K&N air filter.

I wanted to buy a filter for my new Toyota Avensis. It is an eighteen hundred cc petrol powered Tourer and although the original paper filter was adequate, the K&N cotton based filter certainly made a marked improvement in performance. I would certainly recommend others to change to K&N's cotton filters but take advice first regarding your type of engine and what you want from the filter. I have had the filter in the car for about a month now and am going to purchase K&N's Care Service Kit to keep the filter in tip-top condition. When the car comes out of warranty, I am going to make more improvements to the car by using other K&N products. I am a seventy year old who thinks he is forty (so my wife keeps reminding me).
