All aluminum front heat exchanger for the G42, G20 330i/M340i, G22/G23 430i/M440i, G29 Z4 30i/M40i, and A90 Supra. This is a cooler upgrade for the front mount heat exchanger used by the charged air cooler in the intake manifold.

The aluminum construction is far stronger and more reliable than the factory piece that uses plastic end tanks. With the tight space of the engine bay maximizing surface cooling is crucial and CSF has a proven winner in design and materials.

The CSF "Game Over" high performance heat exchanger features:
  • 2-row 42mm core (dual core) featuring CSF’s exclusive B-tube technology
  • Core features an ultra-efficient multi-louvered fin design for maximum surface area contact
  • CNC machined, OEM style “quick-connect” inlet/outlet connections
  • CNC machined, OEM style mounting brackets & fittings for superb fit and durability
  • Includes removable aluminum rock guard
  • 1 hour “mirror finish” hand polish
  • “Drop-in fit” requiring no modifications to install. Accepts all attaching OEM components including “quick-connect” hoses, mounting brackets, and all air ducting/shrouding
  • 2-year warranty
This part replaces BMW part number 17118666811.
