Exclusive to Mace Engineering, here we have our design-registered lower manifold insulatorto suit the Holden series from VS to VY fitted with L67 Supercharged 3.8L 6 cylinder engine.

 

What are manifold insulators and what do they do?

Manifold insulators are a thermal insulating spacer that mount between your 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 about to be that aluminium conducts heat 500 times higher than our composite material!

Also, with gaskets often made out of steel (thermal conductivity of20 W/m-K) placed between the upper and lower manifolds being 0.5mm thick, replacing them with a 25mm manifold insulator will conduct an amazing 3,448 times less heat.

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.

 

Key Benefits:

  • Design registered.
  • Reduces charge air temperature resulting in better power consistency and detonation prevention.

All items fit the Eufy 30C perfectly.
Style: 19 Pack
We bought a Eufy 30C several months ago. After each time it is run, I clean the dust collection chamber, brush dust out of the filter and from the sponge-like pre-filter. After several uses, the filters simply were becoming clogged with tiny dust particles. This kit holds 10 filters and pre-filters, 8 brushes (or four sets) and one main roller brush. Every piece fits perfectly. They look and feel like original quality materials. This is a great set of replacement parts to keep your Eufy working like new.

Works great, easy to setup. It's my second unit for the basement level. Picks up all the fur from a large Rottweiler and a small Rat Terrier.

Not worth it
Style: L50 SES
Worked great for 5 months and then the WiFi connectivity stopped working rendering the vacuum useless. Because it’s refurbished it was past its warranty and the company refused to do anything about it other than offer a discount on a product that cost four times as much even after the discount.

Great vacuum, but it only works on 2.4 GHz Wi-Fi
Style: L50 SES
I missed the last line on the description that states in only works on 2.4 GHz Wi-Fi. I have AT&T fiber and the router they installed only runs on 5.0 GHz. The vacuum still works, but without all of the fancy conveniences. Just be aware of this and if you are not familiar with what it means, check before you purchase one. This is the only reason I am giving it a 4 and not a 5. It is my fault for missing it, so just be aware.
