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!

Really nice and affordable vacuum!
Color: White, Size: D20Plus, Color: White, Size: D20Plus
I’ve been looking to upgrade my vacuum robot for a while. I came across this vacuum, it is affordable and comes with the features that I’m looking for. The strong suction, hair detangle brush (critical if you have long hair) and easy mapping. It honestly made daily cleaning so much easier. The suction power is seriously impressive. It picks up dust and crumbs and I love how it auto emptied the dust bin. Also I have hard floor at home and I’m loving the mopping function. I love how I don’t have to vacuum and mop the floor by myself anymore! Would recommend this robot to people that are looking for an affordable option!

Decent vacuum/mop for the price
Color: Black, Size: D20Plus, Color: Black, Size: D20Plus
We have had this vacuum for a couple of months now and can now give it an honest review. The good: cleans well, good suction power, durable, manages changes in floor height fairly well, attractive (for a robot vacuum), programmable, great mapping The bad: noisy, muffled voices, cumbersome to program initially, app is not the most user-friendly, does not like rugs with a higher nap. Some tips: 1) If you have pets, be cautious of the cleaning solution. Make sure it's pet safe. 2) For pets and children- Remember to pick up any toys before the cleaning cycle begins. The vacuum will try to eat smaller, flat or string toys, and you will end up with a wrapped brush notification. 3) When mapping for the first time, remember to close doors to any rooms or exterior areas you do not want vacuumed or mopped.

Excellent for vacuuming with a great app
Color: White, Size: D20Plus
This thing is just awesome. I gave her name and some googly eyes, and now she is my official cleaning lady. Does a great job with dog hair which was the main reason for the purpose. I was vacuuming all the time. I have hard floors and 3 dogs one of which is a golden retriever that sheds like crazy. The D20 does really great getting up the pet hair along with other stuff in the floor. I have a couple area rugs as well as thick mats in front of the front and back doors, and she does great on both. I definitely make sure to get up any cables or little things like door stops as she will get caught up from time to time. The app works great and does a good job of sending alerts when there is an issue. It lets you know if it’s hung up on something, stick on an edge and if the cleaners are tangled up underneath along with other things. It’s really easy to flip over and take off the brushes to clean them out and untangle them, and easy to put it all back together. You can also schedule her to clean any time of day / night and customize how it cleans certain areas. I prefer to let her run late at night while me and the dogs are sleeping, and she gets the house done in about 90 minutes and covers a lot of ground. She’s also surprisingly quiet for as much as she is picking up. If I’m already awake, I can hear her start to roll around upstairs. But I’ve never been woken up by her, nor have my dogs. I have never used the mop feature as I bought it only for the vacuuming. From what I’ve read it seems there are better options for mopping. But as far as vacuuming goes I am super happy with her! I was vacuuming 3-4 times a week and would usually mop every other week, if ai could get away with it. Now I vacuum and mop once every two weeks, and Dreame does a wonderful job keeping the place clean in between my bi-weekly cleanings. The D20 was a great purchase and a major time and energy saver for me!

Useless
Color: White, Size: D20Plus
Well so far unable to actually use it to see how it works. I have to split my wifi every time I want to use it. It won't charge even when it's on the dock. When I push "charge" on the app it comes off the dock instead of recognizing that it's already on it and proceeds to roam around the house looking for the docking station that it just left. If it can't even find the docking station while sitting on it how can it properly clean the house? I just bought this after returning a defective AirZeen model. Looks like Shark may be the only way to go. Starting yet another return. These are useless

Great Cleaning Power and Super Convenient
Color: White, Size: D20Plus, Color: White, Size: D20Plus
The DREAME D20 Plus Robot Vacuum and Mop works really well in my apartment. The suction is very strong and easily picks up dust and pet hair from both carpets and hard floors. I also like the self-emptying feature with the large dust bag, which saves me a lot of time. The mapping is accurate, and the battery lasts long enough to clean the whole place. Overall, it’s a great robot vacuum for the price.
