AIRTEC Stage 4 Intercooler Upgrade for Ford Focus ST Mk2

The AIRTEC Stage 4 intercooler kit also our includes the 2.5" big boost pipe kit, removing the restrictive OEM Ford 2" boost pipes. We saw gains of 11.8 bhp & 9 lb/ft torque increase over the standard Ford pipes and these gains were achieved by simply bolting on the big AS 2.5" boost pipe kit.

The Stage 4 intercooler kit will easily flow 350 bhp and will see 500 bhp on cars running big turbo conversions.

Features

• High flow 60mm core
• Air-Ram Scoop forces air directly into core of intercooler
• Smooth flow end tanks
• Swayed end pipes
• Increased BHP & torque figures
• Available in Black or Silver
• Fitting time approx. 1 - 2 hours

Fittment: Ford Focus ST MK2

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. Not essential for getting the power you want, just makes cold side hose fit much nicer.
