AIRTEC Motorsport Stage 4 Intercooler Upgrade for Mk2 Focus ST

As part of our expanding Focus RS product range, AIRTEC Motorsport is proud to launch our Stage 4 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 taken our hugely popular Stage 1 Focus RS intercooler and modified it to fit within the ST bumper and modified our 2.5″ big boost pipe kit and modified it to fit the Focus ST turbo.

Our solution to increasing the intercooler’s size and performance within the confines of the limited space behind the bumper is based upon a 60mm core that’s twice as high and almost 100mm longer than the standard item. This offers a massive increase in overall capacity in comparison to the original intercooler, as well as a 127% increase in frontal area over standard, which allows it to make the most of the air flow provided.

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

Matched with our 2.5″ hard boost pipe upgrade that replaces the OEM 2″ pipework. Increasing the dimeter reduces restriction and improves flow, which in turn sees an instant increase in power, as seen during back-to-back dyno testing which saw a huge 11.8bhp and 9lb ft of torque gain simply by fitting the new pipework.

Features:

• Huge high flow 60mm core
• 127% increase in frontal area for improved air flow
• Air Ram Scoop forces air directly into core of intercooler
• Smooth-flow end tanks
• AIRTEC logo brackets
• 2.5″ pipe work improves flow
• Increased BHP & torque
• Pro-Series Black or Natural Silver
• Strongest intercooler available, backed up by our 3-year warranty

Please note: Pipework only available in Pro-Series Black

Important Note: The Pre-facelift ST has a different radiator compared to the facelift & RS, this makes the left hand cold side silicone hose very tight against the radiator cradle. We recommend removing the radiator cradle bolt, levering the cradle to the right and re-drilling a new hole & then replacing the bolt. It’s very simple and easy to do, but is necessary to give you extra clearance for the bigger 2.5″ cold side hose. If you are still not happy with the fit, we would recommend fitting an RS radiator.
