CSF Fender-Mount Oil Cooler Kit – OEM-Plus Design for Porsche 964/993

Description

The CSF Fender Oil Cooler delivers targeted oil cooling for Porsche 964/993 applications, with an OEM-plus design that provides improved oil flow reliability thanks to optimized M30 Widemouth fittings.

This cooler builds on CSF’s proven 911/930 Turbo Fender Oil Cooler heritage, incorporating the same engineered Widemouth approach to improve fluid dynamics and reduce flow restriction for consistent oil pressure under load.

• Precision machined, threaded M30 “Widemouth” fittings — ensure accurate thread engagement and repeatable sealing; the larger, optimized inner diameter reduces turbulence and supports higher volumetric oil flow.
• Widemouth fitting geometry — the widened inlet profile minimizes flow separation at the junction, which matters for sustained cooling performance during high-demand operation and turbo upgrade scenarios.
• Design lineage from CSF 911/930 Turbo cooler — leverages proven engineering intent to deliver consistent thermal management expectations for motorsport and street-driven high-flow systems.

Why this matters: improved oil flow and reduced internal restriction contribute to more effective heat extraction from the engine oil circuit, supporting stable oil temperatures and pressure stability during extended high-load driving.

Technical notes and compatibility considerations:

• Manufacturer: CSF
• Application focus: Fender-mounted oil cooling for Porsche 964 and 993 chassis
• Intended use-case: OEM-plus replacement or upgrade where enhanced high-flow oil cooling is required; suited to performance and turbo upgrade environments that demand reliable oil temperature control
