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.

Arrived opened/tampered
My pack arrived late AND was already opened. Considering this is food, I'm not sure if this is even safe to eat. A real shame since I was really looking forward to having some good biltong.

Hands down my favorite.
Hands down, amazing. Chewy, not overly spiced, lean, and very delicious.

GRISTLE
These are large pieces compared to their other products. So you know, these, specifically my order, has so much connective tissue, that once you're done separating the meat from the gristle, the larger portion is gristle. Flavor is great as usual though.
