Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit the Holden VE series, fitted with the SIDI LLT 3.6L 6 cylinder engine.

 

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:

  • 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.

These shoes make a great first impression, but beware of the stingy toe box.
Size: 13.5 Wide Big Kid, Color: Black/Orange
These shoes make a good first impression. They look sharp and appear to be well-made for running shoes. They also get bonus points for having actual laces instead of the common velco/fake laces combo. However, my son struggled to get them on at first due to limited room in the toe box. He has wide feet as well as high arches and the shoes were very snug across the top of his foot initially. Once he got them on, we determined that they were both wide enough (which is a rarity in itself) and the right size – just tight across the top. I actually had to remove the insoles to get them on his feet at first. After a few minutes I tried again with the insoles and he wore them around the house for a few hours, at which point the upper material had relaxed and/or the footbed had started to take on the shape of his foot, in effect creating more wiggle room. By then he didn't want to take them off, so they must have gotten more comfortable after that brief break-in period. If they were still too tight I'm sure he would have complained. I'll update the review if the shoes wear out prematurely or there is anything else noteworthy to report.

Sole separation
Size: 3 Big Kid, Color: Black/Orange, Size: 3 Big Kid, Color: Black/Orange
I really dont like to write reviews, let alone a negative one. Have had the shoe 1 month and the out sole on both shoes are peeling up. Normally we have had great success with saucony shoes for my boys. But this one we haven't had good luck. I have been super gluing the soles back down everything they peal up. Hopefully this is just a 1 off incident. Both side of one shoe and a large chunk of the heal on the other. You can see the glue marks and separation in pictures.
