Head Cooling Mod HCM
for Ford Mustang 2011-2023 & Ford F150 2011-2020

Manufactured by MMR | Part #455478 or #455478B

Designed to help eliminate hotspots in the #8 cylinder by promoting coolant flow around cylinder # 8 - the cylinder long known to be the first to detonate with aggressive naturally aspirated tunes and forced induction.

Features: 

  • Helps prevent hotspots in rear cylinders
  • O-ring seal & bolt in design cannot leak or fall out like factory freeze plugs
  • Can be used for plumbing dry decked cylinder heads on race applications

Protect your investment with this simple, professional kit. Installation requires tapping out the factory freeze plugs and simply installing the MMR kit.

The kit seals with high-grade O rings (included). The socketless hose does not require hose clamps for simple push-on installation.
