MACE 6.35MM PERFORMANCE PLENUM SPACER FOR HOLDEN CAPRICE WM SIDI LLT 3.6L V6

$140.00

Exclusive to Mace Engineering is our design-registered plenum spacer kit to suit Holden SIDI LLT 3.6L V6 engines.


What is a plenum spacer and what does it do?

A plenum spacer thermally separates the plenum cover and intake manifold. Its main purpose is to improve air distribution between cylinders by slowing down the air speed inside the plenum chamber. As a result there is less of a pressure drop inside the plenum chamber between cylinders, and less air momentum, resulting in better air distribution and power. The change in airflow characteristics is shown in the diagram below.



Not only will our spacer help you make more power, it will also help prevent any costly rebuilds through dangerous lean outs that occur due to poor air distribution with standard manifolds in high horsepower/boost applications. 

In addition to improving air distribution between cylinders, the increase in plenum volume also has a positive effect on bottom end torque.

The fact these spacers are manufactured from the same thermal resistant composite material as our manifold insulators means further horsepower gains are possible due to the reduction in heat soak. 


Key Benefits:

  • Design registered.
  • Reduces charge air temperature resulting in better power consistency and detonation prevention.
