Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit the Ford AU to EL series, fitted with a Windsor EFI 5.0L 8 cylinder engine.


What are manifold insulators and what do they do?

Manifold insulators are a thermal insulating spacer that mount between your engine block and intake manifold. Made from a heat blocking composite, our manifold insulators will increase power from your engine by keeping the intake cooler and increase low end torque by increasing runner length.

 

 

But how do manifold insulators keep the intake manifold cooler?

Given our manifold insulators are made from a composite material with a thermal conductivity of 0.29 W/m*K as opposed to aluminium, which has a thermal conductivity of 150 W/m*K; The difference works about to be that aluminium conducts heat 500 times higher than our composite material!

Also, with gaskets often made out of steel (thermal conductivity of 20 W/m-K) placed between the upper and lower manifolds being 0.5mm thick, replacing them with a manifold insulator will conduct up to an amazing 1655 times less heat depending on the size chosen.

Our composite material also exhibits high stiffness and compressive strength, can withstand temperatures up to 150 °C, and has a thermal expansion coefficient very similar to aluminium to increase sealing capabilities. In addition, the spacer can also withstand boosted conditions with ease.


Key Benefits:

  • Design registered.
  • Reduces charge air temperature resulting in better power consistency and detonation prevention.

Some wrinkles
Size: 17.5" Neck 36"-37" Sleeve, Color: Vert
I would say that it’s more wrinkle resistant than wrinkle free, you’ll probably still have to iron this one. The collar stays are sewn inside the shirt collar so they cannot be changed or replaced (not compatible with magnetic collar stays). Otherwise it fits well and was reasonably priced but not quite what I wanted.

Cell Shade/Sketch Watch conversation timepiece
Color: B White
This is an amazing deal! There’s no question this is an “homage” to the D1 Milano at 1/10th the price! It is lightweight, fits really comfortably, and functions very accurately! Yes, it feels like a light plastic, that’s literally the point. Know this before purchasing. Very stylish timepiece and I plan on buying the black version as well. I hope that they make a lume version in the future! I could just imagine how cool it would be glowing in the dark too! Highly recommend this cool, unique watch and it’s guaranteed to get peoples’ attention!
