CSF’s original Charge-Air-Coolers (Intercoolers) for the McLaren 720S made waves when released in 2021. This system delivered an astonishing 99% thermal efficiency and could be found in the fastest, most powerful McLarens in the world. However, even proven success can be improved. In 2024, CSF went back to the drawing board to address fitment for Spider models and streamline manufacturing amid supply chain challenges.

The result is an all-new, reengineered Charge-Air-Cooler system developed in partnership with CSF’s strategic partner PWR. Compact, more efficient, and now compatible with Spider models, this next-generation system sets a new benchmark in performance cooling for the McLaren 720S, 765LT, GT, plus the new 750S and GTS.

Design & Engineering

This updated system was developed in collaboration with PWR, one of CSF’s strategic manufacturing partners. PWR is known for their motorsports expertise, manufacturing cooling systems for F1, WRC, MotoGP, and more. Together, CSF & PWR have created a high-performance solution tailored for the most demanding McLaren owners, tuners, and race teams.

Both CSF and PWR are Tier-1 OEM-certified cooling manufacturers that specialize in high-performance heat exchangers. These new McLaren Charge-Air-Coolers use advanced core technology, optimized for minimal pressure drop and maximum thermal transfer. Each pair of coolers are made here in the USA with in-house pressure-testing, and quality inspections to meet the stringent demands of McLaren owners. This system delivers unmatched cooling performance for the 4.0L twin-turbo V8 (M840T) found in the 720S, 765LT, 750S, GT, and GTS.

The CSF by PWR Charge-Air-Coolers are handcrafted and professionally TIG welded in the USA. Each unit is made with the highest level of craftsmanship and durability that is unmatched anywhere else in the aftermarket.
