    Before u lash out a few ton on an induction kit maybe u should try the simple yet highly effective de-restricted airbox method, with a larger air intake (either from a Veccy C or Astr VXR) and fit a performance panel filter.

    This will probably give better gains than an induction kit

    De-restricting ur airbox is free - only a few pipes and bungs to remove
    Air intake and adaptor should only cost about £15 total from Vauxhall.
    Air filter should cost approx £30 upwards depending on which one u want (Courtenay sell a re-badged Pipercross foam one for just over £30)

    I think youd be pleasantly surprised with the results the above gives - especially considering ur after performance rather than noise.

    All details regarding the above mods can be found in the HOW TO section.

    Part numbers for larger air intakes are:

    ASTRA VXR
    Main Intake: 55558368
    Adaptor (Intake to Airbox): 55558369

    Vectra C
    Main Intake: 9177099
    Adaptor (Intake to Airbox): 9177104

    Any more Qs just ask

    Obviously 06SXI was referring to closed induction kits which are completely different to open cones - but still seeing as they have a hefty price tag then maybe the derestrict method is the sensible option as ind kits offer not much gain but with a pickup in noise.

    Only u will know the best route my friend - try both and see what ya think.

    you can always sell on the kit u choose not to use

    As you've got a Mk5, you'd be better off getting thre VXR inlet pipeone as it's designed to fit the Mk5 from the outset

    in all honesty a brand new paper filter will have the same effect as a so called "performance" panel filter. The only difference is that the OE one has a lifespan of only a few years compared to the lifetime guarantee (or thereabouts) of the uprated ones.

    As for which one is the best.....Its all down to personal taste and how much money u wish to spend

    Courtenay foam £30
    Pipercross, K&N etc £30-50
    ITG £70+ (no need to oil or do anything - whack it in and leave it) considering the price of oil these days Id be seriously swaying towards this one....its also the same as Ffoeg has fitted to his Z22SE

    If you want a real nice closed induction, BMC i would recommend. But to save hassle with the astras just use the standard gear modified.
