OE 1K0145803D 1K0145803CA Intercooler Charge Air Cooler for Volkswagen Passat Magotan B8 with Lightweight Aluminum Core

This Turbo Intercooler with OE numbers 1K0145803D and 1K0145803CA is a premium aftermarket replacement designed for Volkswagen Passat and Magotan B8. It is manufactured strictly to OEM specifications to guarantee precise fitment and reliable cooling performance for the turbocharged intake system.

As a vital charge air cooler, this intercooler reduces the temperature of hot compressed air from the turbocharger before it enters the combustion chamber. Cooler intake air is denser, which improves combustion efficiency, increases engine power output, lowers fuel consumption and minimizes the risk of engine knock. A damaged, clogged or leaking intercooler usually results in power loss, sluggish acceleration, turbo lag, high intake temperature and engine fault codes, which may cause severe damage to the turbo and engine if left unrepaired.

It adopts lightweight aluminum core and high-efficiency fin structure, delivering excellent heat exchange efficiency and low airflow resistance. Reinforced end tanks and integrated sealing gaskets can withstand repeated pressure surges, thermal cycling and continuous vibration under the hood. Every unit undergoes strict air tightness and pressure testing before packaging to prevent boost leakage.

It supports direct bolt-on installation without extra modification, saving labor time for repair technicians. It is a dependable and cost-effective cooling spare part for auto repair shops, spare parts wholesalers and aftermarket retailers, helping restore stable boost pressure, responsive throttle and normal engine operation for these B8 chassis VW models.
