To fit

Important

To reduce the risk of hoses mounted on the delivery side of the turbocharger coming loose due to low friction at high air pressure, the hoses and connecting pieces must be cleaned thoroughly before fitting. Use a rag dampened with 93 160 907 Motip Dupli cleaning agent to wipe clean inside the ends of the hoses. Clean the connecting pieces as well. If hose clips are rusty or damaged, they must be replaced so the correct clamping force is maintained.
