CSF Front-Mount Heat Exchanger – BMW M3 / M4 / M2 Competition (F8x, S55)

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 published application data for #8075 / #8075V, which includes the BMW i8 (i12). Confirm your exact chassis, engine and model year with Speed Logic before ordering.
• CSF lists the F87 M2 Competition (2019–2021) only; the M2 CS is not on CSF’s published fitment for this part.
