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!

Gets the job done, not sure for how long
Color: Rustic Wood
These were hard to assemble due to the screw needing to go behind a metal bar, meaning all of my shelves are wobbly and one is starting the cave in the corner some. Overall not too bad for the price (got it on sale, wouldn’t recommend paying full price. Also didn’t realize the wood was unfinished so it’s splintery (be careful, I got several splinters when assembling and putting up).

A great $30
Color: Grey, Color: Grey
The wood is cheap particle board (probably better bc they are very light weight) but the brackets are plenty strong and sturdy. Advice on the install: your walls may not be exactly 90 degrees. Install one bracket after the other is holding the shelf up. Super pretty.

Great shelves but be warned.
Color: Grey
These shelves are great for small items and can definitely hold up to their advertised weight if mounted in a stud. However, DO NOT use the longest screws at all. All the screws are low quality and are likely to break. The medium length ones are sufficient for everything. If your wall faces an exterior concrete wall: break off the tips on the dry wall anchors, they are too long.

These are a great corner option
Color: Rustic Wood
Was looking for something to set in some corners, and these fit the bill greatly. They are nice looking and easy to assemble and then put up. They hold a plant and some rock items nicely. A good purchase.
