Factory plastic boost pipes on the MK2 Focus TDCi restrict airflow and can break down as the years pile on — and a split boost pipe means limp mode at the worst moment. This MST Performance silicone boost hose kit replaces them with smooth-bore silicone across the 1.6, 1.8, 2.0 and 2.5 TDCi applications of 2004-2012, upgrading reliability and flow in one job on a car now well into its second decade.
Best For
MK2 TDCi owners pre-empting brittle factory boost plumbing before it fails
High-mileage diesels remapped or towing, where boost pipes work hardest
Pairing with an intake upgrade for a complete breathing refresh
Material: Silicone hoses with a smooth internal bore
Replaces: Factory plastic boost pipe arrangement
Fitment type: vehicle-specific, direct replacement
Why Boost Pipes Age Badly
Boost plumbing lives with heat cycles, oil mist and constant pressure changes; plastic gets brittle doing that job for fifteen-plus years. Silicone shrugs it off, and the smooth interior of these hoses keeps the charge-air path flowing cleanly. Doing the whole intake side? The MST Focus cold air intake covers MK2 TDCi applications too, and MK3 diesels have their own boost hose kit.
Fitment And Setup Checks
Match your engine and years: 1.6 TDCi 2005-2012, 1.8 TDCi 2005-2010, 2.0 TDCi 2004-2012, 2.5 TDCi 2004-2012
MK3 Focus diesels use the separate MK3 kit — check your generation first
Inspect clips and clamps during fitting; renew any that are corroded
Because they fail without warning: age-hardened plastic splits under pressure and the car drops into limp mode. Fitting silicone on your schedule beats a recovery truck on the motorway's.
Does the kit fit all MK2 diesels?
The 1.6, 1.8, 2.0 and 2.5 TDCi applications in the table are covered, each with its own year range — match yours before ordering.
Is this worth doing on a remapped car?
Especially then — a remap raises boost pressure, which is exactly what tired factory pipes handle worst.
