Porsche Exhaust Gasket - Reinz 70-39978-00

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

About Reinz

Founded by Hugo Reinz in 1920, Reinz has been known for the manufacturing of Automotive gaskets for over 90 years. For almost a century Reinz has provided gaskets and sealing products for both auto manufacturers and as an aftermarket solution for car enthusiasts. Their full catalog features over 15,000 different products, providing a great selection for excellent value. Way back in 1962 Reinz became the (OEM) original equipment manufacturer for the prestigious Mercedes-Benz and Volkswagen car companies, a strong partnership that still continues to this day. The company continues to innovate and stay well ahead of the curve. For example, Reinz stopped using asbestos in their gaskets 12 years before it was banned in Germany in 1993. Reinz performs because every part they manufacture meets OEM standards – meaning you're getting great value that you can believe in. Many brands and models use sealing solutions from Reinz. In 1993 Reinx became a partner to the American company, Dana, to form the largest manufactures of components for automobile and commercial vehicles. The Gasket segment of Dana was Victor at the time ahich was then merged with Reinz to form the brand name of "Victor Reinz".
