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!

Very strong perfumed scent
I wanted to love this soap as it sounds like it has a lot of skin loving ingredients, however when I opened the packaging I was immediately disappointed that there was a strong perfumed scent in the soap. I have extremely sensitive skin that flares up easily if I use scented products so unfortunately I didn’t try this soap because of the smell. I took off 3 stars due to the strong smell. If you like perfumed soaps this most likely won’t be an issue. It’s a decent sized bar so that’s definitely a positive note but because of the scent I was afraid to try it. If they make an unscented version of this soap I may give it a try as this one was a no go for me.

Gentle soap, great for hands and body!
I love how gentle this oatmeal soap is. It’s perfect for sensitive skin and doesn’t irritate my hands even when they are rough. I keep one at my sink and one in the shower. The natural scent is lovely and not overpowering. A must-buy for those looking for a mild cleanser!

Itchy, red skin BE GONE!
My 94 year old father has recently had a terrible resurfacing of his psoriasis with red, itchy, flaky sores all over his body! It's been so bad that he can't even sleep at night. My heart has been aching for him BUT he is finally getting some relief from this amazing soap!! I just saw him yesterday and, compared to two weeks ago, the redness and itching has lessened considerably. Plus, he loves the way it smells! What a true JOY to know he is on the mend, in part because of this product. I am about to purchase another bar for my sister who suffers the with the same issue. THANK YOU fo making a product that actually does what it claims to do!!!!!!

Great Product
I’ve been using this all-natural eczema soap for the past few weeks, and I’m genuinely impressed by the results. As someone who has struggled with eczema flare-ups for years, I’ve tried countless products, but this soap stands out. First off, the ingredients are truly natural—no harsh chemicals, fragrances, or preservatives. The soap is made with soothing, skin-friendly components like coconut oil, shea butter, and chamomile extract. It lathers up nicely, creating a gentle, creamy foam that feels luxurious on the skin. What really stands out is how gentle it is on my sensitive skin. Unlike many other soaps I’ve tried, this one doesn’t dry out or irritate my eczema patches. In fact, it has a calming effect and seems to reduce redness and itching after just a few uses. I’ve noticed that my skin feels softer and more hydrated, which has helped prevent flare-ups. The scent is mild and pleasant—not overpowering, but just enough to give you a fresh, clean feeling without triggering any sensitivities. Overall, I’m thrilled with this eczema soap. It’s not only effective at soothing and moisturizing my skin, but it’s also a relief to know that I’m using something that’s completely natural and safe. If you suffer from eczema or other skin sensitivities, I highly recommend giving this soap a try. It’s definitely become a staple in my daily skincare routine.
