Exclusive to Mace Engineering, here we have our design-registered lower manifold insulator to suit the Holden VE and VF series, fitted with the SIDI LF1 LFW 3.0L and LFX 3.6L 6 cylinder engines.

 

What are manifold insulators and what do they do?

Manifold insulators are a thermal insulating spacer that mount betweenyour 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 out 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 3,448 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:

  • (12MM – 10%) (25MM – 13%) increase in bottom end torque.
  • 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.

A good value, works well.
Size: 1 Tier-8.5''Wx10.5''Dx2.5''H, Size: 1 Tier-8.5''Wx10.5''Dx2.5''H
It works great, and a good value for the price. Super easy to install, comes with a template (you probably wont need), screws and a screw driver. Easy peasy It will not affect the performance, but it is a little flimsy. Great service and price. Quality packaged as well.

Great quality product
Size: 2 Tier-5.5''Wx10.5''Dx9.5''H
The product quality is great. Assembly is needed but relatively easy. The moving shelves have a premium slide and catch at the end. I was impressed by this the most. The only potential small issue were the inside protectors it came with. Not that they're poor quality, they have a decent thickness. But during assembly they kept falling out easily because there wasn't enough catch on the shelf itself. In actual stationary use, this may not be an issue. But would have been better if the shelf held onto them more. You may not notice it when you put things on the shelf on top if it but they're also not a great color/texture match. Semi-opaque white plastic on a black metal rack; it cheapens the product. And in case you were wondering, magnets can stick to it. Overall though, I am pleased with the quality of this product.
