AIRTEC Stage 3 is the only off the shelf intercooler that uses a 100mm deep core! we use this core only in the most extreme coolers, we name the 100mm core 'GobStopper' due to it's amazing cooling properties

Every Stage 3 Intercooler comes with a 70mm cold side hose, if you have a big boost pipe kit fitted, your Hot side pipework will still fit.

500+ bhp



We tried a 40mm core and where it worked well but on track we could still see improvements were needed and so we opted for a huge 40mm core normally found on our Cosworth radiators it was perfect!
