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 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.
The OEM tube/fin cores contain a single row 7mm tall flat edge tube along with a high-efficiency multi-louvered 7mm tall fin. The CSF/PWR high performance intercoolers contain 2-row cores featuring 3mm tall rolled tubes with turbulated inner fins manually placed inside each tube to maximize the dissipation of heat from the charge air. The ambient side 4.85mm tall multi-louvered fin is also the most efficient fin in the global high-performance industry.
The advantage of a rolled tube core is the rounded edge which allows airflow to travel around the tube face and into the intercooler core for maximum airflow and heat dissipation (Compared to the OEM flat face tube which scatters airflow when contacting the tube face). Both the OEM intercoolers and the CSF by PWR upgraded performance intercoolers are designed around 87mm thick cores with 103mm wide side channel end plates. This allows for a true plug-and-play "drop-in fit" installation that requires absolutely no modifications to install, and does not require trimming of the expensive OEM carbon fiber air ducts.
