Airtec Stage 4 Intercooler for MK2 Ford 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.

 

Enhance performance during extended periods of hard driving with our modified Stage 1 Focus RS intercooler, now compatible with the ST bumper. The 60mm core, twice as high and nearly 100mm longer than the standard intercooler, offers a significant increase in overall capacity and a 127% larger frontal area. Combined with high-flow end tanks and air diverter scoop for efficient air flow, the AIRTEC Motorsport intercooler outperforms the standard model. Upgrade to our 2.5" hard boost pipe kit, replacing the OEM 2" pipework, for reduced restriction and improved flow, resulting in a significant 11.8bhp and 9lb ft torque gain according to back-to-back dyno testing.

 

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.
