Intercooler Hose Kit Silicone For Audi A3 TT MK1 Turbo Boost PQ34 Platform Replacement
Upgrade your turbocharged 1.8T engine with the Silicone Radiator Hose Kit designed for the Audi A3 TT MK1 and the PQ34 platform. This premium silicone hose set directly replaces aging OEM hoses, delivering superior heat resistance, higher pressure tolerance, and reliable performance under boost. It helps prevent boost leaks and hose failures that can throttle power, especially when you're pushing the engine harder or tuning for more aggressive responses.
Built from high-quality silicone with a 3-ply construction and a robust 4.5 mm thickness, these hoses hold their shape under pressure, resist swelling from heat, and maintain consistent flow through the intercooler and turbo boost pathways. The kit is rated for a working temperature range from -65°F to 500°F (-54°C to 260°C) and a working pressure of 0.3–0.9 MPa (about 3–9 bar), with a bursting pressure of 245 PSI. This combination provides a generous safety margin for everyday driving and performance applications alike.
Applications include Audi A3/TT MK1 on PQ34 platforms with 1.8T turbo engines and compatible VW models such as Golf Mk4, Jetta Mk4, Bora, New Beetle, Scirocco on the PQ34 platform. The kit is designed to directly replace your Original Equipment hoses, supporting reliable operation during upgrades and under high boost conditions.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Benefits & Tips
- Use as a direct replacement when restoring or upgrading your 1.8T Audi/VW intercooler and turbo system to reduce the risk of boost leaks and hose swelling.
- Ideal for performance enhancements: silicone hoses handle higher boost pressures with greater resistance to heat-induced softening compared to OEM rubber hoses.
- Installation tip: inspect surrounding hoses and clamps, route carefully away from hot exhaust paths, and replace clamps for a secure, leak-free seal.
