Information
Exhaust seal ring for heat exchangers.
3 per side. Price is for each.
Exhaust seal ring is designed to replicate the original gasket’s fit and durability, it ensures a gas-tight seal between the exhaust manifold or heat exchanger and the cylinder head—restoring quiet, efficient performance.
Fits:
Porsche 964 C2 / C4 / Carrera RS 1989-94
Porsche 993 Carrera / Turbo 1995-98
Diagram ref no 3
• Seals the connection between the exhaust header / heat exchanger and the engine, preventing exhaust gas leaks
• Helps maintain correct back-pressure, avoids losing efficiency, and ensures proper exhaust flow
Over time, the original seal ring can become brittle, corroded, or compressed, causing exhaust leaks, noise, and potential loss of performance. Installing an OE-Match ring restores a tight, gas-proof seal, helping preserve exhaust integrity and efficiency.
