The turbo intercooler boost hose pipe (OE 39155303 / 39098774) is a direct-fit charge-air hose engineered to channel boosted, cooled air from the intercooler to the throttle body/intake on the Vauxhall Insignia B 2.0 Diesel (B20DTH / D20DTH) engine. This high-quality hose helps your turbo-diesel engine maintain correct boost pressure and airflow, promoting optimum performance, improved throttle response and efficient combustion. When the original boost hose becomes cracked, split or porous due to heat and pressure cycles, it can cause boost leaks, poor acceleration and turbo lag — symptoms this replacement pipe is designed to eliminate.
