These precision machined, threaded M30 "Widemouth" fittings are designed with an optimized inner diameter (ID) to dramatically improve oil flow. These fittings deliver up to 50% greater flow capacity compared to OEM connections.

No change in oil pressure vs OEM.; The original Langerer & Reich oil cooler for the Porsche 964 and 993 was designed back in the 1980s.
