    DeRestrict Air box

    Is this a worth while mod on my gsi?

    I looked at the howto section...... Does those pipes really restrict flow enough to limit bhp?

    Seems a bit strange to me......

    It's worth it as it restricts responsiveness rather than pure BHP, couple it with a vectra C inlet pipe (also in the how to's) and a decent panel filter for the 'full effect'.

    There's plenty of gen if you do a search or check the similar threads at the bottom of this page.

    8 out of 10 astra owners, who expressed a preference, said their cars preferred it

    Do your cars MAFs get clogged up with the oil from your k&n's though?

    as i said to you in the pm i managed 8bhp more out of my sxi with it de-restricted and a panel filter

    prob would have been more if it had the veccy pipe as well

    good mod if you plan to remap it

    Some do but it's usually a sign of over oiling rather than the K7N per se.

    But my 2.2 doesn't have the same maf as most other VX engines, so I can't speak from experience.

    And you must get used to saying "my old ST"

    Can't you just clean them? I got special electrical cleaner spray that dont leave a residual?

    What other filter do you recommend that dont come with as much oil?
