Exclusive to MACE Engineering, our design-registered 6.35mm (1/4") manifold insulator to suit Ford Barra 220 and 230 V8 engines.

 

Key benefits:

  • Produces a cooler intake charge resulting in more power
  • A cooler intake charge also reduces the tendency for detonation, means more ignition timing/boost for more power!
  • Improves low end torque by increasing runner length
  • Better fuel economy
  • Robust insulator material allows it to be re-useable
  • No undesirable side effects


What are manifold insulators and what do they do?

Manifold insulators are a thermal insulating spacer that mounts between your upper and lower 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 out to be that aluminium conducts heat 500 times higher than our composite material!

Also, with gaskets often made out of steel (20 W/m*K thermal conductivity), placed between the upper and lower manifolds, replacing a .5mm gasket with a 6.35mm insulator will conduct an amazing 688 times less heat (yes, that's over 70,000% reduction!). What this basically means is that it becomes very difficult for the engine to heat up the manifold, which ultimately means more power for extended periods (i.e. considerably fewer heat soak issues)!

Our composite material also exhibits high stiffness and compressive strength, can withstand temperatures of up to nearly 150 degrees celcius, 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.

  • Bolt pack
  • Silicone gasket maker

 

What about Installation?

Installation is straight forward, requiring only the removal of your inlet manifold to install the manifold insulators. We currently don't have any fitting instructions for these insulators given the simplicity of the install.

Good buy

A winner with our GSD. He’s not a super aggressive chewer but it has still held up and is a favorite.

Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.

My dog doesn't like it
Size: 5 in, Color: Orange
My dog wasn't a fan of this at all. He was curious about it, probably because he could smell it, but he wasn't sure about chewing it. It could be because his teeth squeak against it? Or maybe it has an odd texture? I don't know But this has sat in the toy bin untouched since the day we got it
