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!

27" monitor mounted easily
Style: Single Arm, Size: 13"-34", Style: Single Arm, Size: 13"-34"
I ended up getting 2 of these monitor arms for the different desks in our office, and I am happy with both of them. The arms are super easy to assemble and adjust to the tension one desires. The arms hold the position where one sets them too, and the gas pistons make it super easy to use. Each arm has a channel on the bottom that allows the wiring to be ran through and hidden, yet remaining accessible if needed. The mounting clamps hold securely and there is no wiggle whatsoever, and it is nice to have a strong feeling monitor mount. It is lightweight and compact so it doesn't feel clunky on the desk. Highly adjustable left to right, up and down, and the screen forward and backward tilt. The price is really good for the overall value and quality of the product. Just make sure to order the right mounting arm depending on the size of your monitor, and you will be fine. Nice quality and feel, and the aesthetics are great too.

Get this one!
Style: Dual Arms, Size: 13"-32", Style: Dual Arms, Size: 13"-32"
I got this dual monitor arm for my home office, and it’s been a total game changer. Having a dual monitor setup makes multitasking so much easier, especially for photo and video editing. Setup was incredibly quick (under 5 minutes), and it feels very secure once mounted. I really like how stable it is and how easy it is to adjust the height and angle. It also helped clear up a lot of desk space since I no longer need bulky monitor stands. Simple design, but it works perfectly. Highly recommend for both single and dual monitor setups. Great value for the price!

Pretty great product
Style: Dual Arms, Size: 17"-33"
Stand works great and as expected. I have a 32” monitor on one and a 26” ultra wide in the vertical position on the other. I’ve had them for a few months and they’ve held tension perfectly. Usually, I find these spring tension arms to become loose after a few months and you just tighten them back up, these are still stiff like when I first set them up, and I move them around quite often. The monitors can rotate 360 degrees and tilt up and down almost 90 degrees each way. The clamp is sturdy so you will feel comfortable making sure it’s tight on the desk. I do plan on drilling a hole to mount the desk to mount it without a clamp and will update my review when I do so. It comes with the hardware to do either mounting options. They're made entirely of metal except for the plastic cable trays that clip along the bottom of the arms. The entire build is well worth the cost and gives me more space on my desk and helps my workflow when editing photos or editing video.

Pretty good product
Style: Single Arm, Size: 13"-34"
Assembly of the actual stand is easy, mounting to a monitor is not because of industrial design fluff. Gotta make the side you DON'T see look "sleek" and "smooth" and "organic" and "integrated" because...reasons. While this is on the manufacturer(s) of the monitor itself, what semi-modern monitor uses 100x100 VESA anyway? The included long screws are too long. Even using the plastic spacers they'll bottom out with a 2mm gap; add washers and it's a lever arm and not solid or confidence-inspiring. I used a die grinder to remove the excess material closer to 75x75 and used the included short screws, perfect. So either include 25mm screws instead of the 30mm (but then the spacers would be too long), or just update the mount plate to 75x75 only, and throw 100x100 "compatibility" into the dustbin of history where absolutely no one will miss it. Arm does move/adjust smoothly and is holding a 34" widescreen where I left it 2 days ago, so it IS a great product once it's properly fitted.

Great monitor arm stand.

Very happy with this product. It's sturdy and easy to install. Love the tilt and swivel feature. The fittings for the stand are very well made. I suggest this for the quality and the price.
