I will be looking to get the THS Intercooler for mine shortly (similar to the APR) but much cheaper.
Ran one on my Mk5 ED30 and made a big difference.
Yes they take a little longer to install than the forge (I was quoted 3/4 hour labour more for the THS) but I really dislike the extra pipe work the forge includes and way it splits the airflow.
@KennyGTI, it's doesn't require any of the coolant dropping or the headlights relignment to install an S3, APR or THS replacement IC
