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!

just buy them
Size: 300 Count (Pack of 1)
Look.. They are paper plates. Are they thin? yes; use two of them, they are cheap enough. If you want "sturdy" to hold your spaghetti or thanksgiving dinner, then use a regular plate and get out of the review section. We use for pizza, sandwiches, hotdogs normal paper plates foods to avoid washing dishes 17times day. If my kids use 25 in one day. so what; each plate cost less than a penny. Bought 300ct in Feb 2025. It's April 2025 and I'm getting ready to place a 2nd order.

Low Quality, High Quantity, But Definitely Overpriced
Size: 500 Count (Pack of 1), Size: 500 Count (Pack of 1)
When did low quality paper plates start costing so much? Yes, you get 500, but these are very thin and I tend to use 2 or 3 at a time, especially when they stick and I don’t want to deal with ripping them apart. These are just ok. Nothing quality about these plates but they do what I need when I use those paper plate holders to keep them supported.

These are excellent plates and made in the USA. There are no substances used in manufacturing that we need to worry about. We’re so glad to have access to these!!

NICE for soups!
Style: 34 Ounces, Size: 34 Count
We try to keep these in the house. They are REALLY nicely sized and work great for soups. They are AWESOME for soups and the only disposable plates I feel comfy using for large stews and such. Makes cleaning easy because I don't HAVE TO CLEAN! They are a bit more expensive than otherd disposable plates, but they are worth it. Pretty heavy duty plates that are thick and great for heavier foods. <3
