AIRTEC Motorsport Inlet Manifold for Focus ST & RS Mk3

As part of our expanding Ford product range, AIRTEC Motorsport is proud to launch our inlet manifold upgrade aimed at modified Mk3 Focus ST and RS owners who want to further improve the performance and potential of their cars for track or fast road use.

Direct Replacement Fit
Designed to fit both the 2.0-litre ST and 2.3-litre RS models, the manifold is a true direct replacement that utilises all of the original fixtures and fittings, including the standard throttle body and therefore pipework.

There are also provisions to fit either the original plastic engine cover or the AIRTEC Motorsport replacement engine cover, and the design also includes a moulded fixing tab to secure the vacuum line, as per the original.

The comprehensive fitting kit includes a thermal gasket to help reduce heat transfer from the cylinder head, together with all fixtures and fittings, new rubber gaskets as well as detailed installation instructions.

Construction 
Made from high-quality cast aluminium for increased strength over the original plastic assembly, the manifold is finished in high-quality powder-coated black with a raised AIRTEC Motorsport logo, for a neat OEM+ look to improve the appearance of the engine bay.

The design also offers improved flow compared to the original, which in-turn offers a notable increase in throttle response. Remapping is not necessary after fitting, but for optimal gains there would be a benefit. 

A key feature of the manifold is its ability to allow an easy solution for extra fuelling capabilities, thanks to the four port injector bosses and fuel rail fittings. This allows additional fuel to be easily added for big power builds without having to use an inlet manifold port injector spacer.

• Cast aluminium construction for improved strength 
• Extra fuelling capabilities with port injection bosses
