The Airtec Motorsport RS-Style Crossover Intake pipe for the Ford Focus ST225 Mk2 has been developed based on feedback from Focus ST drivers who were looking for more efficient airflow, a more aggressive Intake sound and a sleeker look in the engine compartment.
Unlike the original ST Intake system, which winds its way around the engine via several bends and even includes a restrictive 90-degree bend, this RS-style crossover pipe runs directly over the engine to the turbo. This creates a shorter and more efficient airflow with less resistance.
Whereas the original pipework varies from 80 mm to 70 mm and features several constrictions, the Airtec crossover pipe maintains a constant diameter of 76 mm along its entire length. This improves airflow to the turbo, resulting in better response and a sportier Intake sound.
The crossover pipe also allows for the fitting of the massive Airtec Group A air filter for the Focus RS – the largest air filter in the Airtec range for the Focus platform. The original MAF sensor is retained, meaning no adjustments to the ECU calibration are required.
Manufactured from high-quality aluminium and available in a brushed silver finish or a black powder coating. The kit comes complete with a Pro Hoses silicone hose, fitting hardware and a comprehensive installation guide.
Optionally available: a customised vacuum hose specially developed for the modified routing of the Intake system. Airtec recommends this option to ensure correct installation.
Optionally available: an Airtec Motorsport ECU mount/cover made from high-quality plastic. This replaces the original ECU mount and ensures a neat OEM+ finish in the engine compartment.

Frequently Asked Questions
What is the advantage of a crossover pipe over the original system?
The crossover pipe provides a shorter and less restrictive route to the turbo, resulting in better airflow, improved response and a sportier sound.
Does the ECU need to be recalibrated?
No, the original MAF sensor is retained, so no adjustment to the ECU software is necessary.
Can I use the Airtec Group A air filter with this crossover pipe?
Yes, this pipe has been specifically designed for use with the large Airtec Focus RS Group A air filter.
Is the optional vacuum hose necessary?
The crossover pipe can be fitted without it, but Airtec strongly recommends the modified vacuum hose for the best fit and correct routing.
