Pressure Hose / Turbocharger Charge Pipe (Intercooler Hose) – 4K0145738AB

Original pressure hose for the turbocharger system (reinforced charge air hose / intercooler pipe with quick-release couplings), designed for Audi A7 Sportback (4K / 4K8 generation) and Audi A6 (C8 / 4K generation) models with 3.0 TFSI V6 (55 TFSI / engine codes DLZ, DLZA / 340 hp) petrol engines.

Original VAG charge air manifold component. Ensures precise and completely leak-tight transmission of compressed air between the turbocharger, intercooler, and throttle valve, preventing pressure loss, leaks, and power loss in the powertrain.

Fitment guarantee and VIN verification

Every hose undergoes pressure testing, inspection of the condition of the retaining springs in the quick-release couplings, and checking the interior for any oil deposits.

Fitment tip: Pressure hoses in 3.0 TFSI turbocharger systems are selected strictly according to the full part number, including the letter suffix (index AB). Before purchase, we recommend comparing the number on the white label on the old hose or verifying fitment using the vehicle's VIN.
