Tackling heat soak

Post by liffy99 » Sun Jan 01, 2023 11:55 am

Just out of interest but from reading various threads it seems that the initial tuning / mapping possibilities for both the B9 S4 and RS4 are limited by intake temps being too high. I assume down to their respective intercoolers not being able to handle very much more than the factory engine power outputs.

Perhaps the obvious solution is to fit a larger intercooler ( even for stage 1 ?) but does the cold air intake have any effect ? Or do folks fit replacement intakes just for the noise ?
