Technical Data

AIRTEC Motorsport Stage 3 100mm Core Gobstopper Intercooler Upgrade for Astra VXR Mk5

As part of our expanding VXR product range, AIRTEC Motorsport is proud to launch our Gobstopper intercooler upgrade suitable for track or fast road use.

In order to ensure there is no noticeable loss in performance during extended periods of hard driving, we have developed a larger, freer-flowing intercooler that is a direct replacement for the smaller and more restrictive OEM item.

Our solution to increasing the intercooler’s size and performance within the confines of the limited space behind the bumper is based upon a wide and short core with a huge 100mm depth. This offers a massive increase in overall capacity in comparison to the original intercooler, as well as a significant increase in frontal area over standard, which allows it to make the most of the air flow provided.

The outlets of the intercooler increase to 70mm diameter to further improve flow and the full depth air ram scoop helps to direct air towards the core.

Together with our high-flow, moulded one-piece cast end tanks and an internal air diverter to ensure flow is directed correctly and efficiently, the AIRTEC Motorsport intercooler offers much greater efficiency and volume over standard.


Future proof
If you take your power levels to the extreme, our 70mm outlets are ready to cope with bigger throttle bodies and turbo outlets. Custom pipework would be required for over 500bhp.
