Exclusive to Mace Engineering, here we have our design-registered upper manifold insulator to suit Holden Commodores and similar platforms fitted with the RB30E I6 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 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 1,655 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.

Good price and good quality
Material Type: Recycled Fiber, Material Type: Recycled Fiber
I have been subscribing to this Scott Professional toilet paper for over ten years, and it has never disappointed. The 100% recycled fiber rolls are durable and absorbent, and the 2-ply construction offers the comfort and quality we expect from a premium toilet paper. The bulk packaging and subscription model are extremely convenient, delivering every four months—exactly when we need to restock—so we never run out. Over the years, I’ve found this toilet paper to be consistently reliable, making it perfect for long-term use in our household. The product provides excellent value for money, especially considering the combination of quality, eco-friendliness, and bulk quantity. I also appreciate the punctual delivery and ease of subscription management, which eliminates any worry about running low. Whether for home or office use, I highly recommend Scott Professional 2-ply toilet paper for anyone looking for a practical, high-quality, and eco-conscious option that keeps bathrooms well-stocked without hassle.

Better than regular scotts brand
Material Type: Recycled Fiber
It is 2 ply it's not super soft but it's not paper hard either. It's a blend of both. It is absorbent. Septic safe. Does not stick to ur bottom. Lasts much longer. Not so thick but thicker and softer than regular scotts brand.
