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.

Effective tool
Color: Red Trimmer, Size: 4.1"x 2.25"
Simole tool. Does the job. Blades need to be sharp.

You get what you pay for. Won't order again.
Color: Birch, Size: 1/2"x 100ft, Color: Birch, Size: 1/2"x 100ft
Inconsistent width, and soft glue. The veneer is so thin you can see the plywood layers under it in places. The 1/2" width varies from 0.55" to 0.45" and was too narrow to cover the edge of my 0.46" plywood in spots. Even when fully cooled (left some pieces overnight before trimming) the glue is soft and tacky, and loads up on the edge banding trimmer blade. I was able to cover all my pieces, so I still gave it 3 stars. But I won't order it again. It's not worth the couple of dollars I saved. I also ordered a roll of 3/4 and threw it away. Same issues, and the color was way too light (looked more like raw maple than birch)

Nice for cable management
Real metal so it is very sturdy and if you tighten your screw it will be very stable too. I out it next to my monitor mount which provide a nice setup for cable management. It fits perfectly to a VESA 100x100 mount. I have a similar setup in my office but under the desk which makes it versatile.
