Airtec Upgrade Stage 4 Intercooler Kit Ford Focus ST MK2

Airtec Upgrade Stage 4 Intercooler Kit Ford Focus ST MK2

Designed & proven to extract maximum gains from your 300+ bhp ST. Our Stage 4 intercooler kit is the perfect compliment to the DreamScience RSX turbo upgrade or a similar Hybrid/Big Turbo conversion.
The AIRTEC Stage 4 intercooler kit also our includes our 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.

Rolling road tests carried out out at AmD Essex, gains will vary depending on the spec of your ST.
The Stage 4 intercooler kit will easily flow 350 bhp, and will see 500 bhp on cars running big turbo conversions.

Specificaties:

• Air-Ram Scoop, forces Air directly into core of intercooler
• Huge high flow 60mm core, lower ACT Temps
• Smooth flow end tanks, no welds, means no leaks
• AIRTEC logo brackets
• Increased BHP & torque figure, dyne proven at AmD Essex
• Available in Pro-Series Black or Natural Silver
• Strongest intercooler available, backed up by our 3 year warranty
• All pipes have swayed ends to stop the silicone hoses blowing off
• Fitting takes 1 – 2 hours depending on mechanical skill & tools available

Important note: The pre-facelift ST has a different radiator compared to the facelift ST & the RS, this makes the left hand cold side pipe (inlet side) very tight against the radiator cradle & boost hose. We recommend removing the radiator cradle bolt, levering the cradle to the right and re-drilling a new hole & then replace bolt. It’s very simple and easy to do, but is necessary to give you extra clearance for the bigger 2.5′′ cold side pipe. If you are still not happy with the fit, we would recommend fitting a RS radiator. This is not required to get the power you want, just makes cold side hose fit nicer.
