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!

So much fun
My dog is obsessed with this. It comes deflated and you have to pump it but it only takes like 30 seconds to pump. And it comes with the pump which is so convenient! It's nice because you can leave it a tad deflated so your dog can grab onto the ball part if you want. My dog has bitten it a ton and it hasn't popped or deflated yet so it seems sturdy. I like that there are multiple handles because not only does it make it easy to play tug o war but also then you can have multiple dogs playing with it at once. Has held up good over the past week and a great source of entertainment! My dog is about the size of an aussie for reference and it is perfect size for him and small enough for him to carry.

Can’t Take These Off – Ultimate Cozy House Boots!
Size: 12-13, Color: Fleece Black
Okay, I’ll be real — these Men’s Warm Up House Boots have officially replaced my old slippers. They’re insanely comfortable, super warm, and honestly, just make cold mornings way better. The thick Sherpa fleece lining is next-level soft; it feels like walking on a plush blanket ( and that's next ). I’ve been wearing them around the house non-stop ( in fact I'm wearing them now while i'm writing this review ) , and they keep my feet toasty even with tile floors and drafty mornings (New Hampshire winters hit hard). The non-slip soles are great too — I can walk from the living room to the garage without worrying about slipping. They’re flexible like socks but have that extra grip like real slippers. I also appreciate that they’re lightweight and breathable — my feet never overheat like they do in some bulky slippers. The design looks nice too; simple and cozy without being flashy. For the price, these are such a solid find. They feel durable enough to last through multiple seasons. If you’re the kind of person who wants that perfect mix of warm, soft, and practical, these are it. These are great for travel or outdoor lounging. These are a win for winter comfort!

Awesome slippers
Size: 14-15, Color: Fleece Black
Very warm and comfy, I have sasquatch feet (14 wide) and the 14-15 size fit great with plenty of room. It's very hard to find slippers in my size and these are awesome, especially for the price! Definitely recommend these, I've been wearing them pretty much daily around the house during this especially cold northeast winter and they're holding up perfectly.

Warm feet and ankles > everything
Size: 10-11, Color: Red/Black Check
So, I know the foam is going to wear out quick on these, but they are so warm I dont even care. I will update when they start getting beat up. But so far these are great. The soles on these arent the best. Its coushioned now, but even so my foot hangs off it. BUT, it is thick material and its keeping my feet and more importantly my ankles warm. Thats why I bought these. These isnt much on the bottoms to keep you from slipping hut what they have seems to be alright for now on hardwood floors. They fit true to size and are nice and stretchy, just beware the sole is a bit slim. For example my pinky toe hangs off it on both sides almost fully. Still a 7/10 would recommend for lounging around the house.

Warm, comfortable booties
Size: 12-13, Color: Red/Black Check
I would give these booties a 5 star because they are soft, warm, comfortable, high on my ankle and a color I appreciate. They are easy to slip on NOW. I say "NOW" because I have a deformed foot due to being broken. That foot was hard to get the bootie on. After 1 try in which some of the stitching came out; it's easy to put on. The stitching came out far to easily. There are 3 lines of stitching. One line between the sole and 1st layer of polar fleece. That line has had no problem. The other 2 lines have each come out abt 3 inches. I got size 12
