The Airtec 2.5" Big boost pipe Kit is a must-have for any tuned Ford Focus RS Mk3. The kit replaces Ford’s restrictive 2.0" original boost pipes with 2.5" pipework, thereby delivering bolt-on power. The kit has been developed for high-output, remapped Focus RS models.
The pipework consists of 2.5" lightweight aluminium hard pipes connected by 5-ply silicone hoses from Pro Hoses. All pipes feature flanged ends, ensuring the connections remain secure even at higher power outputs and cannot be blown off the hoses.
The kit is a direct replacement requiring no modifications whatsoever. Everything you need for installation is included in the kit, and the pipework is compatible with Airtec, Pro-Alloy, Forge and genuine Ford intercoolers. Installation takes approximately 1 to 2 hours.
The pipework is available in Pro-Series Black.
