Fitted a K&N panel filter to my wife's 2011 Astra 1.6 petrol automatic. With being automatic the fuel consumption wasn't great. After fitting the car was slightly more responsive, but more importantly the fuel consumption was better after checking the average fuel consumption via the onboard computer. Early days but pleased with the product so far.

K&N do great products, if someone said I need a performance air filter, oil filter etc... I would always say K&N. This air filter fitted perfectly on my Astra Mk6 (J) 2012 1.6 Petrol. However, for me, I haven’t noticed any performance difference or quicker acceleration nor have I seen better MPG, this is just city driving. I do regular motorway miles in my car but haven’t done since I bought the new filter so only time will tell if it does make the difference on motorways. The good thing about this product is the million mile warranty which means I don’t have to buy a new paper filter every service (2 x paper filter 1 K and N filter) I make my money back after 2 years of use, all I have to do is clean the filter every 50,000 miles which is good enough for me :) hope this helps anyone thinking of purchasing one of these.

Wasn't expecting much, but I feel like K&N's filters are probably the best in terms of working as advertised. It's not a lot, but there's a noticeable improvement in engine power when I need to accelerate quickly. Plus, my overall average gas economy has improved by about 3mpg. I lease my car, so I wasn't prepared to add much after-market stuff, but this filter was worth the investment!
