CSF High-Performance Charge Air Coolers for McLaren 765LT

Its first supercar performance cooling application, its first McLaren application, and its first application made in the USA. A truly collaborative effort exemplifying the best in the performance aftermarket industry.

Introducing CSF’s new McLaren 720S/765LT High-Performance Intercooler System – the new advantage for the absolute best quarter-mile traps and half-mile speeds, designed for the fastest and most powerful McLarens in the world.

CSF’s complete McLaren 4.0L Intercooler Kit has been meticulously perfected through multiple design iterations of extensive performance and fitment testing. Included as part of the kit, is all the necessary hardware and components for a complete plug-and-play, drop-in solution requiring no modifications to install.

The final piece to the puzzle, and arguably the most important to this project’s development, has been CSF’s new partnership with M Engineering of Southern California – the number one McLaren tuner in the world and holders of numerous McLaren world records.

M Engineering was approached by CSF to not only validate the performance of the intercoolers, but to also take on distribution of the new intercooler kit through their global network of McLaren specialty tuning companies.


The stock intercoolers work phenomenally well and I was hesitant to think they could be outdone after seeing the efficiency of the stock setup.  However, the CSF Intercoolers not only had a higher overall efficiency, but less pressure drop at high air mass flow as well.  The data can do more justice than I can do in words.
