Product Details

ECS Tuning Silicone Turbo Inlet Hose – MINI Cooper S/JCW N14 (R55-R59)

Upgrade your MINI Cooper N14 with our high-flow silicone turbo inlet hose, featuring increased internal volume for greater airflow, a smooth interior finish for an uninterrupted flow path, and more available air for your turbo to consume, resulting in enhanced performance and throttle response.

Unlike the factory plastic inlet hose, which degrades over time and was never engineered with performance in mind, the ECS Tuning replacement features a durable, 4-ply silicone construction with wire reinforcement to handle higher temperatures and boost levels. Reinforced sections help prevent flex and collapse under load, and a smooth internal profile with a counterbored outlet reduces turbulence for optimized airflow to the turbocharger.

ECS Tuning also addresses a known issue where the OEM hose can walk off the turbo inlet and ingest the included gasket, often leading to premature turbo failure. This upgraded design provides a much more secure fit and peace of mind for performance-minded MINI owners.
