The FX "8 Rib" K5 Low Profile Engine Head is CNC-machined from Swiss 7075 T6 and additionally black-coated and laser-engraved for a stylish look. The cooling heads feature additionally drilled holes from the bottom to reduce the weight. The recessed contact area on the underside of the cooling heads – where the combustion chamber insert fits – has had the color coating machined away to allow for the optimal heat transfer. Low-profile engine heads are available in three different sizes for various temperatures. With a lower weight than the standard engine head, they give a lower CG to make the car more stable on fast tracks.

Temperature conditions dictate the recommendations for various different engine heads:
  • 6-ribs – Low air temperature
  • 7-ribs – Medium air temperature
  • 8-ribs – High air temperature
