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!

Dixie Is Good But
Size: 150 Count (Pack of 1)
Dixie paper plates are good but these are better! The durability of them is just as good as Dixie. The leak-proofness is just as good as Dixie. The 10 inch size makes them versatile for everyday use. The main reason why they are better than Dixie is because they’re a lot cheaper and you get double the amount for less $$

Great quality. Don’t think it twice and buy!
Size: 100 Count
When I bought this plates I was not so sure of the quality of the material however, they exceeded my expectations. They are thick and durable. The design and color were perfect and matched with my decoration. The amount of plates for the value was a great deal and I will definitely buy them again and again. Trust me when I say I don’t like most of the disposable paper plates out there and this make a huge difference with how good quality they are and how inexpensive they’re.

Strong Enough for Everyday Use, No Surprises
Size: 150 Count (Pack of 1)
These are exactly what you want from everyday disposable plates. They’re sturdy enough to handle normal meals without bending or soaking through, even with heavier or messier foods. I’ve used them for things like pasta and leftovers, and they held up better than expected for a budget option. The 10-inch size is a good middle ground, big enough for full meals but not oversized. They also hold up fine in the microwave without getting too soft. They’re still paper plates at the end of the day, so if you’re loading them up with really heavy or greasy food, you might want to double up just to be safe. Overall, these are a reliable, no-frills option that works well for daily use, gatherings, or quick cleanup situations.
