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!

Tasty sugar free treat!
My sister is about to begin chemotherapy and her oncologist shared that hard sugar free candies that contain xylitol would be very helpful with the dry mouth chemo is likely to create. I ordered these for her and she says they are delicious! Good natural fruit flavor…tasty for anyone who wants a better quality, healthier (in moderation) sweet treat now and then. Arrived promptly and container was undamaged.

They are yummy!
I prefer the drops instead of the lolipops. I just love the flavors and no sugar or artificial coloring.

It helps with dry mouth!
These really help with dry mouth and the flavors taste good. It doesn't come in a plastic container like the picture which was disappointing. And it is a little expensive but it is a good variety but I do think it would look better in the box shown here instead of in a box. I poured in in another bag.

Less flavor than the pops. Very disappointing.
I bought these after trying the lollipop type of the same brand. Honestly? I was disappointed in the lack of flavor in yhe drops versus the lollipop style. The reason I purchased the drops was because I do not like dealing with the stick of the pop and just wanted the sucker part of the candy. I thought being the same flavors that they would have the same taste. They do not. The drops have much less enjoyable flavor and are quite bland in comparison to the lollipop style. I guess I'm sticking with dealing with the stick to get any good flavor. I also wish the variety of the flavors in both the Zollipops and Zolli Drops was more evenly distributed. The orange are my favorite flavor and the ratio is low compared to the pink or purple and less flavorful pieces. Anyway, just my 2 cents on the difference I noticed between the two variations of the same product.
