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 6.35mm manifold insulator will conduct an amazing 876 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.

Worth the investment! It lasts!!
Color: Medium, Color: Medium
I have been using this religiously as my foundation for over a year! I love it. It works best for me when I use moistuzer, let it dry enough so you have a little slip. A LITTLE goes a long way and double check the bottle because even when it feels empty it’s not fully empty :) it’s not a full coverage approach to foundation I use an elf glo setting over it in winter . It’s light weight and the SPF was what I was looking for!

Expensive, but a good product!
Color: Fair
Love this product. Comes out of the tube white but changes color as you apply. I find you do need moisturizer on your face to get a smoother application - I tend to mix it with my moisturizer before applying and it works well. Am currently on my 3rd tube of the stuff. A bit pricey, but for my skin it sits better than most other products I've tried and doesn't make me break out or look shiny.

the perfect everyday tinted sunscreen! worth the $$
Color: Light, Color: Light
this product was highly recommended to me by my esthetician. I was hesitant to try it because of the price point, but once I learned I could use my HSA funds I immediately purchased! the product is not overly greasy or oily- it gives a beautiful glow. I would recommend setting with a setting spray or powder for longevity. the coverage is buildable, but won't be a fix-all for someone desiring full coverage- as an acne girly, I am satisfied with this product while paired with a few dabs of my concealer. it works well with other colorescience products AND with my other everyday makeup products which was a huge plus for me. it doesn't feel heavy on the skin either which was also a huge selling point for me as someone who needs coverage but hates the feeling of a full face. all in all, I think the product is absolutely worth the money regardless of it being HSA approved or not. I would recommend to anyone who loves wearing makeup but also is looking for something light and effortless. one note about the shade- I have fair olive skin but tan easily, so I got the shade "light" -but I might try the shade "fair" next time as this shade pulls slightly orange on me. the shade matching can be difficult, but I think that's to be expected with a color changing product.

Looks great on my 67 skin!
Color: Medium
Covers well. I love the color. I bought the medium and tan to cover all seasons. I will mix them as needed. It is sticky all day but it looks great so I'll deal with the sticky! I've tried sooo many tinted high SPF moisturizers and I've finally found one that really looks good.

work well
Color: Light
I recently switched to this mineral sunscreen after having irritation and redness from several chemical sunscreens, and it has made a big difference for me. My skin is sensitive, but this one feels gentle and comfortable without causing burning or itching. It gives me good protection and doesn’t leave my skin feeling worse by the end of the day. Definitely a better option for sensitive skin.
