    Default k&n air filter and fuel consumptiom

    My 380 fuel consumption was slowly getting worse over the last 6 months - albeit bumper to bumper traffic i was getting high 15s/16s. per 100ks. Average speed typically under 30kph - strictly heavy traffic driving and no freeways.

    So on the weekend i pulled out the k&n air filter and it didn't look bad at all but thought I would try a fresh paper filter.

    Its early days but I am now getting 13-14 litres per 100 on my same work route -
    and on one day measured in the 11s!! Whats going on here do you think as I must say I am surprised at such a difference..?

    I tried the k&n air filter, and found them to be rubbish the factory paper filter is far better and doesn't cost a fortune.
