Exclusive to Mace Engineering, here we have our design-registered upper manifold insulator to suit the Ford ED to BF series, fitted with I6 engines.

 

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 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 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.

Perfect Suit Great Quality and Value
Color: Lavender Purple, Size: 6 Years, Color: Lavender Purple, Size: 6 Years
I love at how nice this boys suit turned out. The slim fit gives it a stylish, elegant look, and it makes my nephew look so sharp and grown up. Fit true to size. The material feels good quality, not thin or cheap, and it’s definitely nicer than I expected for the price. I really like that it comes as a full set, which made things so much easier instead of having to buy down extra pieces. Love the tie and the vest, so cute. He wore it for a special event and got so many compliments, people couldn’t believe how handsome he looked. It stayed looking neat all day, and he was able to move around comfortably. I could easily see him wearing this again for weddings, church, holidays, or even school pictures. Overall, it’s a great buy if you want your little guy to look dressed up without spending a fortune. Beautiful boys suit, stylish and elegant, great value and quality. Wash inside out, and air dry.

One of the best suits out there!!
Color: Christmas Green, Size: 8 Years
I am not one who write reviews, so the fact that I'm penning this review you should know. These suits are the best, the sizing, the fit, the quality everything is perfect. I bought for my 3 sons and they all fit well, I was worried about the fit because one of my son is slender but tall so length things would be okay but waist toooo big, with this suit everything was on point. Ages: 13-14(about 5"4-5"5 have a little body wouldn't consider husky) got him size 18, 10-11(slender but a little tall for his age) got him size 14, 9yr old(average height and body size) got him size 8. Can't beat the price and for 6 pieces(pants, vest, jacket, shirt, tie, bowtie)

Great buy
Color: Champagne, Size: 6 Years
I bought 3 sizes for my sons to wear at our wedding. They are heavy duty quality material. The dress shirts are a little stiff and snug but also great quality. Would buy again 100%
