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)
  •

    Not a fun install, but worth the effort! 7 months ago
    5out of 5stars

    Figured I’d throw these on while I was resealing an engine I’m using, to get this car around for body work, before turbo swap! It wasn’t fun haha! If you know where everything goes and have a good memory of every piece, it’s worth the effort. The manifold is cold to the touch even after a longer run down the highway. I used to not be able to touch the manifold after a hard run. I gotta stress to you to be careful when installing the EGR tube back on. It needs to be cut in half (I used a small copper pipe cutter for a super clean cut) then use heater hose to extend. The tube does not thread back in easily. Be very careful not to cross thread. Mine did, even with going in hand tight first. Go slow and take your time. Very nice product. I would recommend. I did uses 2 sets of gaskets as recommended. No leaks.

    Installed using no gaskets. Slight bump in low end power and helped smooth out the dead spot in the power curve. Works as advertised.

    QUESTIONS & ANSWERS

    • Q: 1995 Impreza LX 2.2l  mtisdeljr3311 year ago

      Understanding that for the early engine, you have to cut the EGR tube to create length, do you have heater hose you can recommend for this install? I.e. sizing, material? Hose clamps required? Thanks!

        A:  Honestly I have never dealt with an EGR tube extension, but I would imagine it would be as simple as cutting the stock tube, grabbing some 1/2 heater hose(its .5inch if I remember correctly) and then securing the hose to the metal tube with some basic 1/2 inch clamps. Should be golden :)
