IRP aluminium pipes and joiners – the foundation of every professional intake system

IRP aluminium pipes are designed for the extreme conditions typical of motorsport. They offer dimensional stability, excellent heat resistance and high vibration tolerance, making them ideal for upgraded turbo systems, intercooler installations and custom intake setups. Aluminium does not crack, deform or lose its sealing properties – even under sudden load changes that are common in rally, drift or track use.

The rigid structure of IRP aluminium pipes eliminates the risk of collapsing under vacuum and helps minimise pressure losses. This results in faster turbo spool-up, more stable boost levels and a more reliable engine under intense driving. They are the perfect choice for modified turbo builds, track cars, drift cars and demanding rally applications.

Complete flexibility thanks to the wide IRP aluminium range

The IRP product line includes straight pipes, 45° and 90° bends, reducers, T-pieces and a wide range of joiners — everything needed to build a high-efficiency intake or intercooler system. Each element is made from high-quality aluminium with a smooth internal surface, reducing flow resistance and maximising turbo and intercooler performance.

IRP aluminium components are the perfect solution for:

• custom IC piping in heavily modified turbo cars
• upgraded or hybrid turbocharger setups
• custom cold-air intake systems
• advanced cooling system modifications
• engine swaps and bespoke motorsport builds

Why do drivers and tuners choose IRP aluminium pipes?

• High stiffness and dimensional stability – no collapsing under vacuum
• Excellent heat resistance for track and rally environments
• Lightweight construction, easy to modify and weld
• Perfect sealing even under high boost pressure
• Optimised internal flow thanks to a smooth inner surface

Where are IRP aluminium pipes and joiners used?

• Turbo systems (hot and cold side)
• Intercooler installations and charge pipes
• Custom intake systems for NA and turbo engines
• Motorsport cooling systems
• Drift, time attack, rally sprint, track day, hill climb builds

FAQ – frequently asked questions

• Are IRP aluminium pipes suitable for very high boost pressure?
  Yes. IRP aluminium pipes withstand high temperatures and pressure loads, making them suitable for engines running increased boost levels. They maintain full sealing integrity and do not deform, even in extreme track conditions where plastic components would fail.
• Can IRP aluminium pipes be adapted to custom setups?
  Absolutely. IRP aluminium is ideal for TIG welding, cutting and shaping, which makes it perfect for custom layouts, engine swaps or builds requiring a non-standard geometry. They are widely used in bespoke motorsport projects.
• How do I choose the correct pipe diameter?
  The diameter should match the throttle body, intercooler, turbo outlet and other system components. Too small a diameter restricts airflow and affects turbo response, while too large may cause sealing issues. Measuring the internal diameter of the original element is the safest approach — and we can help if needed.
• Are IRP aluminium pipes more durable than silicone or plastic?
  Each material serves a different purpose, but IRP aluminium pipes offer the highest mechanical and thermal resistance. They do not crack, soften or collapse and maintain full stability at extreme temperatures. This is why aluminium piping is the standard in rally and circuit racing applications.
