MACE PERFORMANCE MANIFOLD INSULATOR KIT TO SUIT HOLDEN SIDI LF1 LFW LFX 3.0L 3.6L V6

Exclusive to Mace Engineering, here we have our design-registered lower manifold insulator to suit the Holden VE and VF series, fitted with the SIDI LF1 LFW 3.0L and LFX 3.6L 6 cylinder 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 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 manifold insulator will conduct up to an amazing 3,448 times less heat depending on the size chosen.

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:

• (6.35MM – 5%) (12MM – 10%) (25MM – 13%) increase in bottom end torque.
• Design registered.
• Reduces charge air temperature resulting in better power consistency and detonation prevention.
• Power increase with no undesirable side effects.
• Improved low end torque by increasing runner length.
• Improved fuel economy.
• Easy to install.
• Can be used as a replacement gasket.
• Reusable.
• Proven gains at an affordable price.
