IRP silicone couplers

IRP Silicone Couplers – components engineered for motorsport

IRP silicone hoses are uncompromising components designed for cars operating under high boost pressure, extreme temperatures, and conditions typical for rally, drifting, or intensive track-day use. Their multi-layer silicone structure, strong polyester reinforcement and resistance to deformation make IRP hoses a reliable choice for both heavily modified turbocharged builds and factory vehicles prepared for motorsport.

Compared to traditional rubber hoses, IRP hoses withstand significantly higher loads – they do not swell, delaminate, or lose shape even during sudden pressure or temperature spikes. This is crucial in turbocharged projects where every part of the intake system affects throttle response, boost stability, and overall engine reliability.

Elbows, reducers, T-pieces and specialty hoses for turbo and cooling systems

The IRP range includes precisely manufactured turbo elbows, reducers in multiple diameters, T-pieces, straight sections and reinforced coolant hoses – all designed to operate under high boost pressure. Thanks to the wide selection of diameters and shapes, you can freely redesign your intercooler layout, cold-air intake, cooling system or vacuum installation depending on the vehicle specification and required airflow.

IRP hoses perform exceptionally well in situations such as: – increasing boost pressure, – installing a larger turbocharger or hybrid turbo, – upgrading to a larger or low-restriction intercooler, – building a custom IC piping system, – engine swaps where hose geometry and diameters are non-standard.

Why do drivers and tuners choose IRP hoses?

• Stable operation at high temperatures – ideal for rally stages and long track sessions
• Reinforcement resistant to implosion under high vacuum and deformation under heavy boost
• Compatibility with custom turbo systems, blow-off valves, intercoolers and cooling solutions
• A wide range of diameters allowing precise airflow matching to the project
• Durability proven in rally, drift, sprint and competitive motorsport vehicles

Where are IRP silicone hoses used?

• Turbo systems (hot and cold side), intercooler setups, charge pipes
• Advanced cooling systems in rally cars
• Intake systems in naturally aspirated and turbocharged cars after modifications
• Vacuum lines, boost-control and pneumatic control systems
• Drift, time attack, rallysprints, track-day builds, hillclimb, race and swap projects

FAQ – frequently asked questions from drivers and tuners

• Are IRP hoses suitable for high-boost applications?
  Yes. IRP hoses are engineered to operate in turbo systems generating both factory and increased boost levels. Their multi-layer construction and polyester reinforcement prevent deformation even during rapid pressure spikes. As a result, the intake system remains stable and resistant to leaks. They are an ideal choice for rally, drift and heavily used track-oriented builds.
• Can IRP hoses be used in rally and drift cars?
  Absolutely. IRP hoses are commonly installed in cars competing in KJS, rallysprints, DRIFT OPEN and numerous track-day events. Their resistance to heat, vibration and sudden pressure fluctuations allows them to endure demanding motorsport conditions. They are significantly more durable than standard rubber hoses, which often crack or delaminate under heavy load. IRP hoses maintain system reliability even during long runs or high-temperature operation.
• How do I choose the correct hose diameter?
  The diameter must be matched to the specific component — such as the turbo outlet, throttle body, or aluminium pipe. Too small a diameter will restrict airflow and reduce turbo response; too large may cause sealing problems. In turbo builds it's also important to consider hose stiffness and number of layers to ensure it withstands the intended boost pressure. If unsure, measure the internal diameter of the original pipe or contact us for assistance.
• Why replace rubber hoses with IRP silicone hoses?
  Rubber hoses deteriorate over time — they crack, harden, and lose flexibility, especially in the engine bay where temperatures are high. IRP silicone hoses offer superior resistance to ageing, high temperature and the effects of engine fluids. Thanks to their reinforced structure, they maintain shape under heavy boost and do not collapse under vacuum. This upgrade significantly improves system reliability and eliminates a typical weak point in performance-oriented builds.
