What are manifold insulators and what do they do?

Manifold insulators are a thermal insulating spacer that mounts between your upper and lower 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 then our composite material!

Also, with gaskets often made out of steel (20 W/m*K thermal conductivity), placed between the upper and lower manifolds, replacing a .5mm gasket with a 12mm manifold insulator will conduct an amazing 1087 times less heat (yes, that's over 100,000% reduction!). What this basically means is that it becomes very difficult for the engine to heat up the manifold, which ultimately means more power for extended periods (i.e. considerably fewer heat soak issues, which is especially noticeable on turbocharged cars)!

Our composite material also exhibits high stiffness and compressive strength, can withstand temperatures up to nearly 150C, 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:

  • Produces a cooler intake and intake manifold charge resulting in more power.
  • A cooler intake charge also reduces the tendency for detonation, meaning more ignition timing or boost for more power.
  • Improvelow endtorque by increasing runner length.
  • Better fuel economy.
  • Reusable over and over again.
  • No undesirable side effects.

Great for dry skin. It’s very shiny.
Size: 16.9 Fl Oz (Pack of 1)
This is a wonderful lotion for dry skin. The only drawback that I can see is that it has a slightly oily texture. If you have an issue with dry skin, this will certainly help. I just don’t like the way it feels on my skin all day long.

I absolutely love the Eucerin Intense Repair Body Lotion.
Size: 16.9 Fl Oz (Pack of 1)
As someone with very dry skin and eczema, this lotion has been amazing for my skin. It feels rich, moisturizing, and keeps my skin soft for hours without feeling heavy. Definitely one of my favorites,give me more!

Super effective in making dry skin soft and supple
Size: 16.9 Fl Oz (Pack of 1)
I bought this on a recommendation from my physical therapist post knee replacement surgery. My papery dry skin around the incision was replaced by soft skin, allowing my knee to bend easier, and my physical therapist massaged it into and around the incision.

Best lotion for psoriasis and eczema!
Size: 16.9 Fl Oz (Pack of 1)
This lotions is the only thing that helps my sons eczema and my husbands psoriasis! I like using it too. It stays moist for a little bit but absorbs well. Smell is very light and doesn't have artificial fragrance which I love. Pump never gives issues, easy to lock and open.
