Exclusive to Mace Engineering, here we have our design-registered lower manifold insulatorto suit the Holden series from VS to VY fitted with L67 Supercharged 3.8L 6 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 of20 W/m-K) placed between the upper and lower manifolds being 0.5mm thick, replacing them with a 6.35mm manifold insulator will conduct an amazing 876 times less heat.

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.
  • Power increase with no undesirable side effects.
  • Improved low end torque by increasing runner length.
  • Improved fuel economy.
  • Easy to install.
  • Can be used as a replacement gasket.
  • Reusable.
  • Proven gains at an affordable price.

Good ink
Color: BCMY
I like this ink, it has never failed me. You do have to be careful when using it or it will make a mess. It is hard to remember which needle was used for the color, the second time they are used. Washing them out still leave a small amount of color but not so much that it will change the color.

Exelente
Color: BCMY
Excelente tinta para sublimación. Los colores salen vivos y muy bonitos en las impresiones. Las botellas son fáciles de rellenar y compatibles con mi Epson EcoTank. Hasta ahora la calidad me ha gustado mucho y las impresiones quedan nítidas y profesionales. Muy recomendada para comenzar en sublimación

Great color, not easy to refill
Color: BCMY
Love this ink, but I do wish that it was easier to fill. I have to use a syringe to refill my ink... I'm using an epson ET 16600.
