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 about 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:

  • (6.35MM – 5%) (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.

Fabrics Great, Size a little Big, Overall Pretty Good
Size: Medium, Color: Dark Navy
This suit was truly great, the size for the pants and the vest were pretty on point, maybe a little long for the pants. The jacket was way too big though compared to the rest. Overall pretty good suit for the price, very surprised at the build quality and faabrics.

Nice pants.
Color: Deep Gray, Size: 10
These are nice pants for a boot to wear to a formal event. I got these for my son to wear to a wedding. They fit him good and he said they were comfortable. The material seems decent for the price. He wore them one before out growing them but that is expected with kids.

Baggy hips
Color: Light Gray, Size: 6, Color: Light Gray, Size: 6
These gray dress pants don't fit perfectly but the size range it so wide that it's expected. My 5yr old is tall for his age but he's thin with a small waist. Pants made with adjustable waists are ideal if we get them long enoughlike a 6 or 7. There biggest flaw in these pants is that the sides (or thigh areas) are so baggy the form a weird pouch. Much like most pants heel probably outgrow the length before he can fill in the hip and waist areas. Other than that, the color is a soft gray. The material is thin but it irons quickly. It's overall quality used fair so if your kid is average height and weight, this might fit perfectly.
