PERFORMANCE 12MM PLENUM SPACER FOR CAMARO 3.6L LLT V6

Key benefits:

* Provides better air distribution between cylinders, resulting in more power
* Produces a cooler intake manifold charge resulting in more power.
* Improvement in low end torque by increasing plenum volume by 18%
* Better fuel economy
* Reusable over and over again.
* No undesirable side effects

What is a plenum spacer and what does it do?

A Plenum spacer is a special spacer that sits between your plenum cover and intake manifold. Its main purpose is to improve air distribution (like our twin throttle manifold) 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 hence an increase in power.The change in airflow characteristics is shown in the diagram.

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

In addition to improving air distribution between cylinders, the increase in plenum volume also increases low down torque.

Made from the same thermal resistant composite material as our manifold insulators, our plenum spacer helps keep power outputs constant due to the reduction in air temperature. For further information about the material properties please check out our manifold insulators.

What's included

Plenum spacer, longer plenum screws, spacer bushes and gasket maker. Basically everything you need for the installation.

What about installation?

Installation is very straight forward, requiring only the removal of your engine cover and plenum cover to install the plenum spacer.
