Silicone turbo intake VW Golf III 1.9 TDI AHU 1Z AFN FVMQ — REDOX

REDOX silicone hose for the turbo intake circuit of the VW Golf III 1.9 TDI (AHU/1Z 90 hp and AFN 110 hp, 1993-1999). Garrett turbo hot post-charge air and PCV blow-by oil vapours mandate the FVMQ fluorosilicone inner liner.

Why FVMQ is mandatory

Without FVMQ, the hose softens, blisters and loses sealing — a frequent cause of boost leaks, blue smoke and underboost on ageing AHU/AFN.

Technical construction

• FVMQ inner liner
• Multi-layer VMQ outer
• Polyester woven reinforcement
• 5 mm wall
• -50/+200 °C continuous
• 65-75 Shore A hardness

Benefits vs OEM

Long-term thermal stability, shape memory, ozone/UV and chemical resistance. Suited to 25+ year-old Golf III TDIs where OEM hoses are almost always end-of-life.

Delivery

Hose supplied alone. W4 stainless clamps recommended. Plug-and-play.
