The OEM McLaren charge-air-coolers offer up to 94% thermal efficiency, but their brazed tanks can burst at higher boost pressures, and CSF's original 99% efficient design had fitment issues on Spider models. This reengineered CSF by PWR system delivers exceptional performance in a more compact package that fits all GT, GTS, 720S, 765LT, and 750S variants.

The hand-built bar/plate cores are manufactured in PWR's Tier-1 OEM facility in Indianapolis to aerospace-level tolerances, with 3 times as many fin rows as the factory tube and fin core and a much higher burst pressure rating that takes the stress of boost spikes far better than tube/fin designs.
