CSF Front-Mount Heat Exchanger – BMW S55 (F8x)

OVERVIEW

CSF's front-mount heat exchanger is the charge-cooling upgrade for the S55-powered F8X BMW. A 2-row 42mm dual core built on CSF's exclusive B-Tube technology replaces the factory unit, with a 45-row design that fits without any modification to the car.

A dual-pass flow structure — the same architecture BMW uses — routes the charge coolant across the core twice before it exits, producing the lowest outlet temperature possible from this package. CNC-machined OEM-style quick-connect inlet and outlet connections, CNC-machined OEM-style mounting brackets and fittings, and an all-aluminum race-style drain plug make it a straight swap that reuses every attaching factory component, including the quick-connect hoses, mounting brackets, OEM X-brace and all air ducting and shrouding.

A removable aluminum rock guard protects the core from debris. Two finishes are available: a polished silver unit and a satin black version.

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 hoses, brackets, X-brace and ducting.
• Installer-supplied: fresh BMW-spec coolant for the charge-air circuit to refill and top off after the swap, plus a drain pan.

Installation

• CSF does not publish a downloadable installation PDF for this heat exchanger. Printed installation instructions are packed in the box.
• Installation uses the OEM mounting points and quick-connect fittings; no cutting, drilling or line modification is required, and the factory X-brace and ducting reinstall unchanged.
• Bleed the charge-cooling circuit fully after refilling before the car is driven hard.
• Need help before or during the install? Contact Speed Logic and we will walk you through it.

Notes

• Fitment above follows CSF's current published application data for #8075 / #8075V, which expands CSF's "F8X" shorthand into the individual F80, F82, F83 and F87 body codes and also lists the i12 i8. Confirm your exact chassis, engine and model year with Speed Logic before ordering.
