    I was planning on replacing the standard airbox and was wondering if a BMC Carbon jobbie would work well. I'd like to make up/buy a heatshield like the one that is included in the Dahlback kit. Does anyone use one of these just now and is it any good?

      The pic show something very similar to the heatshield included with the dahlback kit , I think I may have very rough dimensions somewhere , I'll have a look

        here it is very rough as I mentioned . the tab piece is bent and should have a hole through it which fits into the original screw fixing point of the airbox assemby down beside the wg and turbo.

            Cheers mate, I'm away back offshore next week, so I might try making up a stainless one whilst no one is looking . I've emailed Dahlback about purchasing an induction kit minus K&N filter, so going to see if they come back with anything. I'll definately need to source the 180 degree bend from somewhere, as we don't have anything of that diameter in stainless aboard! A friend has a BMC on his GTI-6 rallye and he seems pleased enough with it, so I imagine it would be a decent enough thing.

              I think it'll still cost you around £130-150 for the h/shield and the pipe bend assembly, alloy or silicon bend are readily available , many threads in the forum showing different variations on a theme, don't think using s/s would give you any great advantage over the cheaper alloy/intercooler pipes on the bay etc

                  Is there much difference between the 3b and aby box and do you just need the box and filter or anything else? How much are they to buy and where can I get one from

                    Is this a straight swap for the S2 item, or does or does it also require RS2 MAF?

                        We've tried using both open-air kits, and stock airboxes and aby and also RS2, the RS2 is the best one, even with the open-air kits included, on a really really cold day, with a medium temperatured engine, I would GUESS that the open-air kit would perform about the same as an RS2 airbox.

                        However we modify our airboxes to an RTM version .

                        This is how it looks.

                        RTM



                        erixon is the engineer of this amazing airbox

                        And of course. After this mod, this box outperforms the RS2 ones. When we finish rebuilding erixons engine, we will take the car to the drag strip and see how fast the box can go (rs2 turbo and em + RTM mods)

                          To swap them you will also need the plastic behind the headlight since the 3B has a slot and the ABY box has a round inlet

                            Anyone know what the best mod is with an S6/S4 with all that extra room we have.
                            I want to have a nice sound (cone) but I want to have the best gains (k&n in the airbox by all accounts), any ideas?

                              Why not get one of the RTM boxes as that would make the sound plus flow better and they do sell them.
