    Default AEM Cone Air Filter flange size

    Hi all,

    I just ordered a crossover delete (more for the sound than anything, getting a FMIC at a later date) and MAF extension. However, I'm having trouble determining exactly which flange size a cone filter needs to be able to slide over the end of the MAF.

    CourteneySport seems to say 76mm internal diameter:

    eBay seems to say 83mm internal diameter:
    https://www.ebay.co.uk/itm/ASTRA-VXR...4AAOSwiwVWTZ1e

    Additionally, I accidentally stumbled across kopite81's (Danny's VXR) build thread where I was able to lift the model number from a picture of an AEM Cone Filter they brought which has an 83mm internal diameter flange:

    Furthermore, in kopite81's build thread, you can clearly see the filter fitted very nicely:

    CourteneySport sell the 21-203DK
    eBay sells the 21-2110DK
    kopite81 has the 21-2113DK

    So I'm confused... do I need 76mm or 83mm?

    Thanks to everyone in advance.

    Kinda answering my own question here, and confirming my suspicion - early this morning I got under the bonnet, removed the pipe leading from the stock air box to the MAF, and grabbed a grabbed a ruler.

    Boring story short, the the pipe that leads from the stock air box to the MAF has two different internal diameters depending on which end of the pipe you're measuring (it's a reducer pipe - in reserve).

    The air box end (stock air box) is approx' 76mm internal diameter, and the MAF end is approx' 83mm internal diameter.

    If anyone knows any different please let me know.

    I have an AEM 21-2110DK on order, so I if it fits properly I'll update this thread for clarity.

    Something else I've learned is that the black AEM filters, although they look cool, are the "Brute Force" edition of the Dry Flow series of AEM filters and are designed for off-road applications. These filters are denoted by "BF" on the end of the product code instead of "D" or "DK" and as such I suspect the "BF" filters have significantly less flow compared to the "D" or "DK" filters owing to their use case.

    I ordered mine from Nevlock too. Looking at your photo it looks like the 21-2110DK is the correct one - thanks!
