This air cooler is a staggering twice as thick as the standard part on the car. Its made from pure aluminium, and helps cool the supercharged compressed air, thus improving on power and efficiency. Unlike the original, this air cooler doesn't use plastic crimps end tanks and doesn't deteriorate like the original. Complete with all relevant bracketry. Each one is bespoke hand-fabricated, therefore some of the brackets will require careful measuring and holes drilling, where relevant, to fit your model of car. Recommended for warmer climates. Also recommended for a tuned car running additional boost via supercharger pulley upgrades. We also have the ability to run a separate header tank on the XF x250, separating it from the engines main cooling system, also adding security/reliability to the cooling system, helping again to keep lower temperatures. This part fits: Supercharged All Jaguar XF x250 (2007-2015 shape) Supercharged All Jaguar XJ x351 (2010-2020 shape) Supercharged All Jaguar F type Supercharged All Jaguar XK
