AIRTEC Motorsport Stage 3 Intercooler Upgrade for Focus RS Mk2

Technical Data

AIRTEC Stage 3 is the only off the shelf intercooler that uses a 100mm deep core!

We use this core only in the most extreme coolers, we name the 100mm core ‘Gobstopper’ due to it’s amazing cooling properties

The AIRTEC Stage 2 had already proved itself in the Focus RS tuning scene as the must have mod for 400bhp+ cars, we wanted to take the Stage 3 to a whole new level and it took over 10 month’s to get perfect.

Every Stage 3 intercooler comes with a 70mm cold side hose, if you have a big boost pipe kit fitted then your hot side pipework will still fit.

Features of Stage 3:

• Smooth flow curved end tanks, for that ultimate flow
• Cold side intercooler end tank made with 70mm outlet to match the throttle body outlet
• 70mm 3pce alloy silicone cold side hose
• Huge high flow 100mm core AKA ‘The Gobstopper’
• Air-Ram Scoop, forces Air directly into core of intercooler
• Fitting takes 2-3 hours max, NO Bumper removal required
• Increased BHP & torque
• Available in Pro-Series Black
• Strongest intercooler available, backed up by our 3 year warranty.
• Made by Europe’s No.1 intercooler supplier for the Mk2 RS

Test results:

AIRTEC Stage2 Intercooler – Max power 594.2 bhp & 546.3 lb ft torque 

• Run 1 Air temp into Intercooler 164 degrees & Air temp out of Intercooler 25 degrees
• Run 2 Air temp into Intercooler 163 degrees & Air temp out of Intercooler 27 degrees
• Run 3 Air temp into Intercooler 168 degrees & Air temp out of Intercooler 28 degrees

Gains of 37+ bhp peak & 54 lb ft torque increase. This was simply by swapping from stage 2 to stage 3. Please note if you were fitting stage 3 on a 400+bhp car you would not see gains like above, this intercooler was designed for Genuine 500+bhp cars. It will still be an improvement for a car running 400+bhp however the gains seen may not be as seen above.

Approximate dimensions:

220mm height

100mm thick

940mm wide

Please note: When fitting, please be sure there is sufficient clearance against any sharp edges on the radiator. The hose must be angled a certain way to avoid this.
