    Hi guys, been looking into getting a fmic for my leon cupra whilst i got this time off for the lockdown and ive been looking at a few universal kits on ebay but they all seem to have the dodgy looking pipes coming out the sides of the intercooler that just look gross when fitted cause you lose your grills and fogs, anyone know what pipes/bends to order which would mean i dont have to lose my fogs ? Got a pre facelift front bumper as well
    Cheers

    Look for one that fits the octavia vrs as it has the same auq lump and ko3s as the cupra

    back in the day i ran a THS FMIC although i cannot for the life of me find in in todays marketplace

    All i found was if the pipes look neat and hidden then theyre usually custom made

    Yes the 150 golf has the ko3 and the 180 has the ko3’s

    pipework runs same direction and inlet manifolds all on the left when looking into the engine bay

    Pass no idea

    i fitted a golf mk4 gti auq fmic to my octavia vrs

    i have no experience of fitting one to a leon, guess just depends how much room is behind the leon bumper.

    anything can be made to fit thats for certain if you got one that suited a golf mk4 or octavia vrs it would give you a good starting point.

    I have also been looking quite heavily into Toyo set ups etc recently. I believe Forge FMIC is twinpass for AUQ rather than single pass. Airtec im not sure about but they're so very expensive that i have just researched universal set ups so far.

    Regarding size, as that is what seems to be missing from pretty much every single thread ive researched, I found this useful piece of information:

    "The size of the core you need depends on the application. For smaller turbos such as the k03s we don’t want too big of a core as you lose the low down punchiness that the small turbos are renowned for. It has been found that the Toyosports 550x225x63mm matches perfectly to the smaller sub 300bhp turbos flow and gives sufficient cooling of the charge air."
    (source: https://18t-tuning.co.uk/intercoolers/)

    Sadly this particular size of cooler is out of stock, and ive yet to recieve a reply from toyosports about restocking.

    Points to note (im looking for information so please correct me where im wrong):

    • Its to my understanding that for the AUQ we need 64mm/2.5" pipework.
    • Some people have said that going for a tall cooler is pointless as its blocked by the bumper, which makes sense to have one take up below the crash bar rather sitting than behind it, but is that a sacrifice in performance just to avoid cutting the crash bar?

    What i'd like to know is, what size is effective vs the biggest/smallest I can go without losing fogs and cutting the crash bar to sh*t? Is there any point in the ko3s models having one a FMIC take up that much space? So many questions lol.

    Gokiwi, does it save the fogs because the core is taller and not as wide? Or is it due the pipework?

    Sadly doesnt give us the core size in the listing description

    For ease of use on the stock turbo why not just do the arch mod and use an uprated side mount intercooler, more than enough for a ko3s
