CSF Race-Spec Engine Oil Cooler – BMW N54 (E-Chassis)

OVERVIEW

CSF's Race-Spec cooler for the E-Chassis BMW replaces the factory oil/transmission cooler with a far more capable unit built on CSF's AC condenser technology. Where the OEM cooler uses a ten-tube core, CSF packs in eleven super-high-pressure micro-tubes and wraps them in a high-density multi-louvered fin, producing roughly 20% more surface area contact than the factory part. In CSF's own lab testing the result is approximately 30% more heat rejection than the OEM cooler.

The cooler is a true drop-in. It accepts every attaching OEM component — oil-line connections, mounting brackets and the factory shroud and ducting — so no lines need to be modified or re-routed. CSF markets this as the world's first genuinely plug-and-play transmission cooler for the E9X M3 platform; on manual-transmission cars the same unit serves as an upgraded engine oil cooler.

TECH RESOURCES

Additional Parts Required

• None. CSF Radiators specifies no additional hardware for this part — it is a direct-fit replacement that reuses the OEM lines, brackets and ducting.
• Installer-supplied: a drain pan and fresh fluid to replace what is lost when the cooler and lines are opened.

Installation

• CSF does not publish a downloadable installation PDF for this part. Printed installation instructions are packed in the box with the cooler.
• Installation is a direct swap of the factory cooler using OEM mounting points and quick-connect oil lines; no cutting, drilling or line modification is required.
• Need help before or during the install? Contact Speed Logic and we will walk you through it.

Notes

• Years and models above follow CSF's current published fitment for #8042. CSF's catalog title for this part also covers the E8X 135i, and CSF's US table does not separately list the E93 convertible — the E93 rows are carried over from Speed Logic's original CSF fitment data. Confirm your exact chassis, engine and transmission with Speed Logic before ordering.
