Intercooler Kit Courtenay Sport - Astra H VXR / Zafira B VXR Big Power Evolution
Our Astra VXR Bigger Power Intercooler is an evolution of our original intercooler, the original was a 3 way joint development venture between ourselves, Pro Alloy & 888 Race Engineering who were running the Vauxhall BTCC race team at the time, it was also approved for aftermarket fitment and use in the PTCC (Production Touring Car Championship) a championship we won twice at the hands of racing supremo Adrian Churchill.
The Evolution Intercooler is a deeper cored version of the original and has been developed for big power cars that run without Air Conditioning.
The core is now 24% deeper utilising the space that the AC condenser and fan used to occupy. As before it is still full height front mounted intercooler for maximum cooling of the inlet air. It features a high-quality tube and fin core which is both more efficient and significantly lighter than the cheaper bar and plate cores, giving the best flow and heat rejection cooling characteristics possible. This core that is both wider and taller than the original and is more than twice the depth of the original factory intercooler. The kit comes with all mounting brackets, enlarged 60mm alloy pipework and silicone hose set / joiners.
In tests we have seen excellent results high horse power cars both on road and track with significant and sustained cooling drops even on heavy track use on cars up and over 550 Bhp.
Available in silver or satin black stealth look
Additional air guides are available to help guide air through the core.
