One of the FMIC options for the Mk7 GTI is an eBay product that operates in parallel with the GTI stock intercooler.
This test was to determine the airflow through the pair of intercoolers connected as they would be on the GTI. On account of the bi-cooler arrangement, positioning the intercooler pair so that they could be flow tested took some extra work.
These latest results, combined with previous measurements, are shown on the chart below:
The addition of the eBay FMIC to the stock GTI intercooler increases the airflow over the stock GTI IC by 34%.
Jeff — is the second result (DF) from a different bi-cooler configuration?
The red bar that is labeled eBay DF is just the single larger eBay intercooler that is a direct replacement for the stock GTI IC. The flow testing was documented in this post:

Thankyou for your efforts! I am very confused how running the two in series INCREASES flow
The bi-cooler arrangement has the intercoolers in parallel.
What would happen if you ran these in a series? Could it potentially cool better?
There’d be more pressure drop. I don’t know if it would cool better, I think it is unlikely to make an improvement that would be worth the effort.
