PLEASE NOTE:These Manifold Insulators will vary depending on engine design and model so we strongly recommend you look here and view your vehicles engine code before proceeding. These kits do come with bolts however due to the large variances of these High Feature V6’s we cannot guarantee the fitment of the bolts as well as the Manifold Insulators themselves. If in doubt please take photos and measurements of the manifold runners and bolts as we would better be able to assist.


Key Benefits:

* Produces a cooler intake and intake manifold charge resulting in more power.
* A cooler intake charge also reduces the tendency for detonation, meaning more ignition timing or boost for more power
* Improve low end torque by increasing runner length.
* Better fuel economy
* Reusable over and over again.
* No undesirable side effects

What are manifold insulators and what do they do?

Manifold insulators are a thermal insulating spacer that mounts between your upper and lower 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 out to be that aluminium conducts heat 500 times higher than our composite material.

Also, with gaskets often made out of steel (20 W/m*K thermal conductivity), placed between the upper and lower manifolds, replacing a .5mm gasket with a 12mm manifold insulator will conduct an amazing 1087 times less heat (yes, that's over 100,000% reduction!). What this basically means is that it becomes very difficult for the engine to heat up the manifold, which ultimately means more power for extended periods (i.e. considerably fewer heat soak issues)!

Our composite material also exhibits high stiffness and compressive strength, can withstand temperatures up to nearly 150C, 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.

Dyno Results

The following test was conducted on a 2007 model Holden Statesman, with a standard Alloytec 6. Looking at the graph, we can see that power produced down low had increased by a staggering 10%! While power also increased virtually across the entire rev range. Please note that these results don't reflect the true nature of the on road gains given the lack of actual airflow, which further drop inlet temps.

Under these normal driving conditions the plenum (upper manifold), with the insulator in place, becomes cool enough to comfortably touch. Unlike before, without the manifold insulator installed under the same driving conditions, making it very difficult to touch without getting burnt!
