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 25mm manifold insulator will conduct an amazing 3,448 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.

High quality, durable, loved by my chewer *
Size: Medium (Pack of 1), Style: Stick Medium
Excellent chew bone Toy for aggressive chewer. I've purchased this same brand bone/ Toy for several years. One lasts at least 1-2 years ( if it doesn't get run over by a lawn mower). Lol. I usually pay $8-$9 for one in retail stores. This is an excellent price at $6. Squeaker stops after a few months but my Field Spaniel dog is deaf now anyway! He loves chewing on this for his gums and when people are gathered in the same room he just starts chewing and enjoying himself in the midst of fellowship.

I got this for my 95lb lab who is an aggressive chewer thinking that it looked durable and would last a while. He tore it apart within an hour and I had to throw it away.

Felt durable but it couldn’t hold up
Size: Large (Pack of 1), Style: Stick Large, Size: Large (Pack of 1), Style: Stick Large
I really thought my pet wouldn’t be able to destroy it but it’s in tiny pieces in the trash now. we played together and she was gentle I guess because she didn’t bite or tug hard at all I left her alone with it like I’ve done before but this time she broke it down in chunks. Did not have this toy for more then 24 hours.

Great fun & strong!!!
Size: Large (Pack of 1), Style: Stick Large
These are the best sticks ever! Our dogs chew and slobber all over these for sometimes an hour at a time. They like the “give” texture when they chew it. Imagine an indestructible, gummy bear! Because of their softness, they don’t end up with sharp edges or texture, although they are sturdy, and very durable. We have had these for our two dogs for close to a month now and it is their go to indoor to stick. The gentle squeak is not loud and obnoxious, but a playful sound that has them coming back for more with each chomp! If you love your dogs, this is the cheese stick for them. He’s also make an excellent fetch stick as they can go inside or outside. They wash off easily with water. This is a great investment, especially if you’ve been wasting your money replacing toys for strong jawed dogs!
