    K & N air filter

    Hi Guys,
    I have a 1993 Patrol with 4.2 petrol with 200,000km on it.
    What is the truth about K & N air filters?
    Do they really give better economy / power?

    Thanks.

    Neil.

    I have one in the GU, and I think it definitely makes a difference, getting more air faster.
    Buy once, very easy to clean and re-oil.

    Me too. I have a second to swap over at service time to make things quicker.

    Is the slightly less filtration an issue? would it do any harm if you drive on very dusty roads?

    I can't really answer that but I know I would rather have longevity than a small increase in power but each to there own

    The trick to engine longevity is lack of filter maintenance. True story. The build up of dust and crap within the filter helps to improve its filtering and preserves engine life.
    IMO and should be taken with a grain of salt.

    From what I have read, the K&N filters better than a paper filter at high air speeds.
