SUV Hose Kit VAG 1.8 T 20V 150/180 HP

Product description: SUV kit for 1.8T 20V engines

Maximize the performance of your 1.8T engine! This high-performance silicone hose kit. It is the ideal solution to fix the well-known problem of gradual power loss in the 1.8T.

While the standard bypass valve (SUV) is often located in an extremely hot area in front of the intercooler, our kit relocates the valve directly in front of the throttle body on the cold air side. The key advantage: Only air that has already been cooled circulates. This protects the valve’s sensitive diaphragm from thermal damage and ensures higher air density in the intake system – which directly leads to better cylinder filling and noticeably more power.

- Package contents:

• 1x high-performance silicone main hose (multi-layer fabric-reinforced)

• 1x flexible vacuum hose

• 2x aluminum angle connectors (high-gloss polished)

• 1x connector adapter / T-piece

• 1x set of stainless steel hose clamps (precision fit)

• 1x set of cable ties for secure fastening

- Technical specifications:

• Optimized airflow: Relocation of the valve from the hot air side to the cold air side (after the intercooler).

• Thermal protection: Prevents the typical "hardening" and leakage of the diaphragm caused by heat exposure.

• Performance boost: Improved turbocharger response and a more stable boost curve.

• Material: Extremely heat-resistant and pressure-resistant silicone for maximum durability.

• Flexibility: Fully compatible with the original bypass valve or upgrade piston valves.

• Efficiency: Higher air density ensures optimized combustion and power delivery.

• Audi A3 (Type 8L)

• Audi TT (Type 8N)
