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!

Tastes Great & Actually Works!
Size: 100 Count (Pack of 1)
I was honestly surprised by how good these Benefiber chewable tablets taste — no weird texture or aftertaste at all. They’re super easy to take, especially if you don’t like mixing powders into drinks. Best of all, they really work! I noticed a difference quickly without any discomfort. This has become a daily staple for me, and I love how convenient and effective it is. Highly recommend if you’re looking for an easy fiber boost that doesn’t feel like a chore.

Fiber That's Actually Fun!
Size: 100 Count (Pack of 1)
Who knew fiber could be this enjoyable? Benefiber's chewable tablets have turned my daily routine into a flavor-packed adventure. Pros: Delicious Flavors: These assorted fruit flavors make taking fiber feel like indulging in a treat. No Water Needed: Pop a tablet and go—no need to chase it down with a glass of water. Digestive Dynamo: They work wonders for keeping things moving smoothly, if you catch my drift. Cons: Sweet Tooth Alert: They are a bit sweet, so if you're cutting back on sugar, keep that in mind. In a nutshell, these chewable fiber tablets have made me a fiber fan. If you're looking to add some zest to your digestive health routine, give them a try.

Love these instead of gummies!
Size: 100 Count (Pack of 1)
I grew tired of the brand name gummies I had been taking for years and switched to these about 2 weeks ago. I love them! I enjoy chewing them because they taste good and aren’t so sticky (I have TMJ/bite/jaw issues). I much prefer these and they work very well to keep me regular. I’ve converted to these now and got a subscription for them.

Be careful! Will have extra impact with any adolescents but especially boys.
Size: 100 Count (Pack of 1)
Well these tablets taste intensely sweet. There is no possiblity that any of the orginal flavor might be detected. They chew with vigours crunching noises. The directions don't say anything about taking it with food but I think it was faintly better with food than an empty stomach. On the whole the experience was like eating candy. But you gotta be careful about how they work. Like any fiber you need to get used to taking it and in the interim you will experience gas and bloating. It's been ten days since I started and the gas hasn't gone away. The tablets seem to take about 24-48 hours before I could perceive any effect. I don't perceive ANY softening of the stools. They seem to be as hardened as ever no matter how much water I drink before, during or after. . However the amazing amounts of gas produced propels the pellets out as if from an air gun. You should not allow any adolescents anywhere near you. You will instantly aquire a neighborhood wide reputation for setting the longest fart record *ever*. The gases do coincide with the number of intervals between doses so pellets are expelled with projectile force at regular intervals during the day. While the results may seem unimpressive apparently they add up and I no longer experience blockages. 5 stars normally but extra stars because your kids will regard you with new respect.
