    Found out i have a small split in my brake booster hose from my inlet to the master cylinder so this could be the problem with my poor idle

    Does anyone have the part number for this pipe and the rubber grommet that sits in the master cylinder

    Also my maf died today but lucky me i have two spares in the boot 10 mins later everything is well. This mafless tune i have been looking into is starting to look better for me so i've ordered some 4 in boost hose and a big ass Blitz stainless steel filter

    Do you mean the kind of U bend on the end of the inlet manifold.
    I bought a Ebay item like a Forge one and its been spot on.

    Probs be best to get some heatshielding down there otherwise the heat will just kill another hose when refitted.
