Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit the Holden VZ and VE series, fitted with an Alloytec 3.6L V6.

 

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.

 

Dyno Results:

The following test was conducted on a 2007 model Holden Statesman, with a standard Alloytec 6. Looking at the graph, we can see that power produced down low had increased by a staggering 10%! While power also increased virtually across the entire rev range. Please note that these results don't reflect the true nature of the on road gains given the lack of actual airflow, which further drop inlet temps.

Under normal driving conditions the plenum (upper manifold), with the insulator in place, becomes cool enough to comfortably touch. Unlike before, without the manifold insulator installed under the same driving conditions, making it very difficult to touch without getting burnt!

Would not buy again
Flavor Name: Peanut Butter, Size: 6.9 Ounce (Pack of 1)
Would not order these again. Opening in bone is too small making it almost impossible for even a small dog to reach peanut butter inside.

Perfect size
Flavor Name: Peanut Butter, Size: 6.9 Ounce (Pack of 1)
I like this size. I’ve gotten the larger ones in the past, but my 45 pound dogs can’t get to the center. This size works much better for them. They love them.

my dog says NO
Flavor Name: Peanut Butter, Size: 6.9 Ounce (Pack of 1)
My dog sniffs both ends of this bone then walks away. I see in inside of it is very hard so I decided to soak it in some hot water for awhile and see what she does with it. If it works I will update. Update. Soaking didn't help. So that bone went in the trash.

My dogs love them
Flavor Name: Peanut Butter, Size: 4 Ounce (Pack of 1)
My dogs love these. They don’t last very long but my dogs are big, and they aren’t messy. I also like how they don’t stink like some chews.
