CSF Porsche 964/993 OEM+ Performance Fender Oil Cooler

CSF drew additional inspiration from its proven 911/930 Turbo Fender Oil Cooler (#8168), incorporating similarly engineered Widemouth fittings. 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. Each stainless steel fitting is crafted in-house for superior strength, durability, and long-term reliability under pressure. To ensure a perfect, leak-free seal, CSF pre-installs the fittings with high-quality copper crush washers.
