Scope of delivery: - 1x 1.8T upgrade hose for crankcase - 2x hose clampsDescription: A weak point of the VAG 1.8T engines is the standard hose between the crankcase ventilation and the intake manifold. This tears due to the pressure in the intake manifold. This allows the boost pressure to escape. In addition to a sudden, or even gradual loss of power, 1.8T engines without a MAP sensor also have an excessively rich fuel mixture as a result. The upgrade hose offered solves this problem thanks to the significantly more robust rubber compound and high-quality clamps. A must for 1.8T engines.Suitable for: 1.8T AGU | 150 hp (110 kW) 1.8T AQA | 150 hp (110 kW) 1.8T ARX | 150 hp (110 kW) 1.8T ARZ | 150 hp (110 kW) 1.8T AUM | 150 hp (110 kW) 1.8T AJQ | 180 hp (132 kW) 1.8T APP | 180 hp (132 kW) 1.8T ARY | 180 hp (132 kW) 1.8T AUQ | 180 hp (132 kW) 1.8T AMK | 210 hp (154 kW) 1.8T APY | 210 hp (154 kW) 1.8T AUL | 210 hp (154 kW) 1.8T BAM | 225 hp (165 kW)
