Technical Data
As part of our expanding Ford Focus product range, AIRTEC Motorsport is proud to launch our header tank upgrade to suit Mk4 ST models.
A direct replacement for the original plastic tank, the AIRTEC Motorsport header tank is made from lightweight aluminium and comes in a high-quality powder coated black finish. It also features a sight glass to view the coolant level and comes with an uprated high-pressure cap.
The tank uses original fixing points, hoses and connectors so no drilling or cutting is required and fitting is a simple process.
With an improved look to the engine bay and increased strength so the tank will not leak over time, this is a simple yet effective upgrade.
