Features & Product Details

RallySport Direct proudly carries quality aftermarket performance enhancements and solutions brought to you by GrimmSpeed. 

 

These are the GrimmSpeed Phenolic Thermal Spacers. These thermal spacers have been designed to absorb the heat that generates between the intake manifold and the engine block. When running the factory gaskets only, the intake manifold can get very hot to the touch, and that unnecessary internal heat gets cycled back through the engine leaving much room for improvement. GrimmSpeed has come up with a great solution by creating a set of phenolic spacers that are available in a variety of thicknesses to absorb that heat to drastically reduce the transfer of heat from the engine block to the intake manifold. The result is a 1% increase in horsepower for every 5 degrees of heat reduction.

 

 

 

DETAILS:

  • 8mm in thickness
  • Designed to absorb the heat from the engine and the intake manifold
  • Reduces heat soak
  • Super durable phenolic material construction 
  • Creates cooler and denser air which increases the amount of air that mixes with the fuel which improves the overall efficiency
  • Every 5 degrees in temperature drop will increase the horsepower by 1%
  • Direct bolt-on installation
  • Can withstand operating temperatures past 500°F
  • Capable of conducting 300-900 times less heat when compared to the steel intake manifold gaskets
  • Sold as a pair
  • Includes longer bolts due to compensating for the ticker phenolic spacers
  •  

     

     

    NOTE:

  • It is recommended to use (2) sets of intake manifold gaskets on each side of the spacers (sold separately)
  • When installing on the Impreza Phase 1, you will have to cut your EGR tube in half and insert a heater hose between the halves of the EGR tube to extend it
  •

    QUESTIONS & ANSWERS

    • Q: Turbo fitment?  James6149 years ago

      Do you know if these will fit the 93-96 WRX EJ20G engine? If not, do you guys carry spacers that will fit those engines?

        A:  I'm sure we have a spacer that will fit but we will need you to email us with a picture of your head profile so we can confirm which spacers will be compatible. [email protected] Mike
