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!

Sturdy paper bowls, economical quantity purchase
Size: 300 Count
I previously bought 50 (?) of the paper plates to check the quality and see how well they hold up before making quantity purchases of other paper products. The bowls hold up well though I use them primarily for cut up avocados, sliced tomatoes, cole slaw, etc. I have used them in the microwave under 15 seconds to reheat toasted English muffins with marmalade with no problem. I use Pyrex glass bowls in the microwave for veggies and soups, so I am unable to speak on how well the bowls hold up with hot foods in the microwave. I resisted buying and using paper bowls and plates for a long time; however, with my 80th birthday fast approaching, the fewer dishes I have to wash means less time standing on my feet. I am an experienced shopper, and these quality paper products bought in bulk are the best buy I have found. I recommend them.

Strong and very convenient
Size: 50 Count
These paper bowls are sturdy and hold up well even with hot or liquid foods. They don’t get soggy easily and are microwave safe, which makes them very convenient. The size is also great for soups, cereal, or leftovers. Good quality for disposable bowls and very practical for everyday use.

Sturdy, great value, very utilitarian
Size: 50 Count
Exactly what I wanted. Exact quality thickness and sturdiness. Only small downside is they're coated in a wax like substance and stick together so you have to pry them apart and if you microwave something, it tends to meld together and also stick into the bowl. But I still love them especially the price.
