    mk4 astra, vectra intake fitting

    Hi all,

    yesterday i ordered the two parts from vauxhall

    9177104 - hose piping adaptor (not sure if required or not yet)
    9177099 - vectra c 2.0 diesel air intake

    both of which cost me about £15 inc.vat

    i have been looking over loads of diffferent forums and am still slightly unsure on the best method for fitting. many people say that it is a very tight fit.
    I have already de-restricted the airbox.
    My car is a 1.8 mk4 sport 3dr hatch x18xe1, anyone done the same mod any tips would be appreciated!

    Cheers

    Sorry to pull it off topic, but is the airbox mod the same as what I did on my VX220 - drill a large hole with a hole saw in the airbox next to the existing intake and fit an additional pipe?

    No it's removing the two pipes on the inside of the box to open up the flow.

    There's a How To for this (and others) - click my sig if you've not discovered them yet

    job done, you really need to twist the hose adaptor 90 degrees and squash it up tight as **** for it to fit in!

    definitely pleased with the difference this mod has made. More pull in high revs (4800+) and it will pick up quicker and with mayb a smidge more power from low down revs.

    recommended mod! :-P

    Nice one, that is what i was wanting to hear, also did you derestrict the airbox at the same time? I wasnt too sure if was gonna be worth it but for £15 its not really all that much.
