Since the vehicle’s release, the only Porsche 991 GT2 RS intercooler upgrade was not an upgrade, but a band-aid for the stock 1990’s style water spray system which sprays water from a reservoir in the frunk and onto the intercoolers. The band-aid was to install a larger capacity water tank which simply delayed the inevitable running out of water and output to be automatically limited by the factory ECU to try to keep the engine safe. Until you refilled the reservoir again it’s likely your 991 GT2 RS would struggle with charge temps and limited output.
Experts in cooling CSF and PWR have joined operations to deliver a High-Performance Intercooler upgrade for the 991 GT2 RS which eliminates heat soak and lowers charge air temps on stock, tuned, and tracked cars. CSF achieves this by using an F1 performance-grade core which dramatically improves the efficiency of the intercoolers within the same space constraints.
