Audi Intercooler - Mahle Behr 376747521

Product Information

An intercooler is a heat exchanger used in turbocharged or supercharged engines to cool the compressed air before it enters the engine’s intake manifold.

Purpose:

• Reduce air temperature: Compressed air from the turbo or supercharger heats up; cooler air is denser and contains more oxygen, which improves combustion efficiency.
• Improve engine performance: Cooler, denser air allows more fuel to burn, increasing power.
• Protect the engine: Reduces the risk of knocking and excessive thermal stress.

Intercoolers can be air-to-air (uses ambient air to cool the compressed air) or air-to-liquid (uses a coolant or water). They are typically mounted in front of the radiator or in a dedicated location in the engine bay.

• Reduced Engine Power or Boost: Leaks or blockages prevent the engine from receiving properly compressed, cooled air.
• Hissing or Whistling Noise: Air escaping from cracks or loose connections under boost produces noticeable sounds.
• Increased Intake Air Temperature: Engine may run hotter, reducing performance and efficiency.

About Mahle Behr

Mahle Behr GmbH & Co. KG is a German corporation active in the automobile industry, headquartered in Stuttgart-Feuerbach. It is a specialist for automotive air conditioning and engine cooling systems. Mahle began in 1920 when pistons made of heavy gray cast iron were being used in internal combustion engines for automobiles and there was a need for a new design. The Mahle brothers countered this trend by producing light-alloy pistons at their small, newly established company however the technology was still finicky and problems come up frequently. They soon determined that they needed to come up with a solution to keep dirt and dust out of the engine so they eventually developed air and oil filters as well. Their perseverance paid off and the light-alloy pistons began to take over the market. Today, half of all automobiles produced worldwide contain MAHLE components. MAHLE offers an extensive range of parts for everyone including pistons, cylinder liners, piston ring sets, bearings, assemblies, valves, valve train components, and air, oil, fuel, and cabin air filters. Their catalog and online database of aftermarket engine components is an indispensable reference.In early 2016, Stuttgart-based MAHLE GmbH increased its holding in the Behr Group from 36.85 percent to approximately 51 percent with the acquisition of all shares in the BWK GmbH holding company. The company now goes by Mahle-Behr.
