Exclusive to Mace Engineering Group, our design-registered and new generation universal cold air intake box to suit Holden Series VL to VS is a direct drop-in replacement for your existing air box assembly.

This kit includes no pre-cut holes (besides the mounting holes) and is perfect for custom work involving aftermarket setups such as larger hole diameter requirements and different mounting positions giving you the option and freedom to alter your intake to best suit your current custom setup.

Key Benefits:

• Genuine bolt on product, does require minor modifications.
• Huge cold air entrance, maximizing the amount of air captured behind the headlight region.
• Made from a heat resistant extruded ABS plastic, ensuring your filter remains cool maximizing power, unlike other steel or aluminium enclosures on the market.
• Won't rust or discolour like powder coated or aluminium enclosures on the market.

Contents:

• 1 X Air box
• 1 X Black cover
• Mounting hardware required for complete installation

Vehicle Fitment Guide

These heavy duty head gaskets are manufactured from composite graphite which is known for its stability at ultra high temperatures. The stainless steel fire rings prevent any sort of warpage and degradation that other gaskets may experience when exposed to the same harsh environment.

Specifications:

• Material: Graphite
• Thickness: 1.18mm

Key Benefits:

• Premium quality components and materials.
• No re-torque required.
• Abrasion resistant graphite is suitable for bi-metal (alloy head applications).
• Suitable for standard and performance builds.

Contents:

•  2 X Cylinder head gasket

Vehicle Fitment Guide

Exclusive to Mace Engineering, this cold air intake is a direct drop-in replacement for the existing air box assembly in Holden VL and a simple DIY modification would be required for VB to VK series.

Key Benefits:

• Design registered.
• Genuine bolt on product, which comes with everything required for installation.
• Utilizes a pod filter which offers superior flow characteristics compared to conventional panel filters. It is airflow meter safe which means it won't coat the heater elements in your airflow meter with oil which have been known to cause dangerous lean outs.
• Huge cold air entrance, maximising the amount of air captured behind the headlight region.
• Made from a heat resistant extruded ABS plastic, ensuring your filter remains cool unlike other steel or aluminium enclosures on the market.
• Won't rust or discolour like powder coated or aluminium enclosures on the market.
• On road power gains of around 10kw at the rears are not uncommon, depending on modifications.
• Improved drivability and throttle response.

Contents:

• 1 X Air box
• 1 X Adaptor tube
• 1 X Bolt pack
• 1 X Black cover
• 1 X Hi-flow pod filter (Airflow meter safe) 

Vehicle Fitment Guide

Note: The air box lid will not be able to cater for the VR-VS washer bottle. To get around this, you can re-size the length of the filler neck, however this isn't recommended as it means you'll need to run a smaller pod filter, restricting the amount of air the motor can intake.

This performance 82°C thermostat suits Holden Buick LN3 L27, Ecotec L36 and L67 Supercharged 3.8L V6 engines.

Key Benefits:

• Drops engine temperature by 10°C.
• Prevents overheating and improves performance.
• DIY installation.
• Super-affordable performance modification.
• Up to 30% higher coolant flow in comparison to standard replacement items, due to larger cross sectional area and more stream lined features. 

Why

Heat is the single biggest killer of performance and can actually damage your engine if its exposed to extreme temperatures for a extended time frames. Avoiding heat in its various forms will not only help boost your engine's performance but also ensure that power levels are consistent and reliable.

A cheap way to reduce coolant temperatures in these engines is by installing one of our 82°C thermostats.

What

Factory-supplied thermostats begin to open at 92°C. This is far too high for a performance application. At this temperature, your engine could begin to suffer from pre-ignition (detonation) or at the very least the ECU will retard the ignition timing to prevent detonation, robbing you of precious horsepower.

How

Our 82°C thermostat opens much earlier than the factory item, allowing coolant to flow through the engine from the radiator much sooner. This limits the peak engine temperature by 10°C, preventing overheating.

With your engine running consistently cooler, your horsepower levels across the rev range will be more consistent and reliable which is especially good for boosted applications or even when towing on hot summer days.

Note: For an L67 engine, installation will require the removal of the supercharger.
