Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit the Nissan R31 Skyline fitted with an RB30 3.0L 6 cylinder engine.

 

What are manifold insulators and what do they do?

Manifold insulatorsare 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 toaluminium, which has a thermal conductivity of 150 W/m*K; The difference works about to be thataluminium 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 12mm manifold insulator will conduct an amazing 1655 times less heat.

Our composite material also exhibits high stiffness and compressive strength, can withstand temperatures up to nearly 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.
  • Power increase with no undesirable side effects.
  • Improvedlow end torque by increasing runner length.
  • Improved fuel economy.
  • Easy to install.
  • Can be used as a replacement gasket.
  • Reusable.
  • Proven gains at an affordable price.

 

Contents:

  • 1 X Pair of 12mm manifold insulator

Vehicle Fitment Guide


Note: Depending on the inlet manifold type, these manifold insulators may require longer manifold bolts for installation.

Make your Cappuccinos!
Color: White
I purchased this after a trip to France. I drank a lot of cafe cremes, pretty much like a cappuccino, and decided I need it in my like every day. Easy to use. Didn’t come with instructions but I was able to figure it out. Takes a little time but works well for what I want to achieve. Love the glass pitcher. Doesn’t spill when pouring. It’s very quiet while frothing super easy to clean. I love it!

Great frother
Color: Matte Black
It makes a great milk froth and heats well. One thing however, in spite of respecting the line limit it spills out and you have to clean the whole thing. So don’t fill it up to the line limit.

Thick foam for Cappuccinos
Color: White-Stainless, Color: White-Stainless
Comes with sevaral options including thin and thick foam, hot milk and cold foam. I used the thick foam for cappuccinos and I was impressed by the consistency. Not so much noise and easy to clean. The frother tools come off easily for cleaning the pitcher.

Very slow--5+ minutes to froth and warm milk
Color: White-Stainless
Pros-- Makes nice froth and warms the milk. Both froth settings produce the same kind of froth. it's relatively easy to clean-- usually just a strong rinse will do. It does fine in the dishwasher too. The noise level isn't bad. Cons--it takes between five and six minutes to froth milk. It is very slow. I can froth latte art milk on my espresso maker in less than a minute, by comparison. The forth it produces is too thick to make any kind of latte art.

Quality
Color: White-Stainless
What really impressed me is how fast it works—in just a couple of minutes, I have hot, creamy milk with thick, rich foam. The texture comes out smooth and fluffy, just like a coffee shop. It’s super easy to use, and cleaning it is quick too. I’ve used it for lattes, cappuccinos, and even hot chocolate, and it works perfectly every time. Definitely worth it if you want something quick, easy, and makes great foam in large amounts
