BMW 335D Silicone Intercooler Boost Hose Upgrade E90 E91 E92 E93

Price range: £49.99 through £79.99

Description

A common issue on the E Series 335D is intercooler boost hose failure, as the standard OEM hose cannot reliably handle high pressures or repeated heat cycles. This 335D Intercooler Boost Hose is a high-performance replacement specifically designed for MTC and Forge fittings, ensuring a secure and reliable connection. Please note: this hose is not compatible with standard factory fittings.

Constructed from five reinforced silicone layers with integrated metal rings, this hose is engineered to withstand extreme boost pressures without expanding or deforming under load. The fluoro-lined interior resists discoloration and material degradation, ensuring a durable, long-lasting finish that maintains consistent airflow and turbo efficiency.

This hose is an ideal solution for both oil leaks and boost leaks, restoring full system integrity and reliable performance for daily driving, spirited street use, or high-performance applications. Its reinforced construction maintains consistent boost pressure, improves throttle response, and enhances overall turbo efficiency under demanding conditions.

Configurations & Colours

The 335D Intercooler Boost Hose is available in red, black, or blue, allowing you to match your vehicle’s aesthetic or performance build. Multiple configurations are offered to suit different setups:

  • Boost hose only – simple replacement for worn OEM hoses.

  • Boost hose with two aluminium ends – ideal for upgraded or custom intercooler systems.

  • Boost hose with one aluminium end – flexible option for hybrid setups or partial upgrades.

These options make the hose perfect for custom builds, performance upgrades, or direct replacement of worn components, giving enthusiasts the flexibility to achieve a professional and reliable setup.
