Audi VW Exhaust Manifold Gasket - Corteco 03L253039B

Product Information

The exhaust manifold gasket is a component that forms a seal between the engine’s exhaust manifold and the cylinder head. The exhaust manifold is responsible for collecting exhaust gases from the engine’s cylinders and directing them into the exhaust system. The gasket’s primary function is to prevent exhaust gas leaks and ensure that exhaust gases flow smoothly into the exhaust manifold and through the exhaust system. It ensures that all exhaust gases are directed into the exhaust system rather than escaping into the engine compartment, which could lead to dangerous fumes entering the vehicle's cabin and a foul odor.

• Exhaust Leaks: A common sign of a faulty gasket is a hissing or tapping sound, especially during acceleration or when the engine is cold
• Reduced Backpressure: exhaust leaks affect the backpressure needed for efficient engine operation, leading to poor performance
• Odor: A leaking gasket may cause exhaust fumes to escape into the engine bay or even the cabin. This can lead to a noticeable, strong smell of exhaust gases (such as unburnt fuel or sulfur) inside or near the vehicle
• Overheating: A leaking gasket can allow hot exhaust gases to escape into the engine bay, potentially causing nearby components (like hoses, wires, or plastic parts) to overheat, melt, or become damaged

Originally founded in 1849 as a leather tannery Freudenburg started making seals in 1932 with the invention of the Simmerring®. This seal style quickly replaced felt seals as the new standard for radial shaft sealing rings for rotating shafts/assemblies. Freudenburg began engineering and manufacturing vibration control technology with shock absorbers and bushings in 1957. It was in that same year that Freudenburg partnered with an Italian seal manufacturer Corte & Cosso, creating the Corteco brand. Continuing their history of innovation, Corteco introduced Micronair cabin filters in 1989 and quickly became the market leader in cabin filtering technology.
