Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit Chevroletvehicles fitted with Alloytec LY7 3.6L V6 engine.

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 out 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.

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 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!

Parts Guide

Please select the part number you require from the variation by utilising our vehicle fitment guide and parts guide.

Notes:

  • The Manifold Insulator may vary depending on engine design and model so we strongly recommend you lookhere and view your vehicle's engine code before proceeding with your purchase.
  • This Manifold insulator kit does come with bolts however due to the large variances of the High Feature V6 engines, fitment of the bolts as well as the manifold insulators themselves, cannot be 100% guaranteed. If in doubt, please share photos and measurements of your vehicle's manifold runners and bolts with us only then we would be able to assist better.

Beautiful space friendly
Color: Brown, Color: Brown
Absolutely love these three piece shelves, they were perfect for where I wanted them to be placed. They give that corner such a great look. I love that they can be used face up or down. The color I chose is exactly as described and made of real wood thick and slightly heavy., easy to install perfect for any corner especially when space is limited. Would absolutely buy another set!

does the job and looks nice
Color: Brown
these shelves are nice. they look good and hold a reasonable amount of weight. I will say, they don't sit perfectly flush work the wall... maybe they were built incorrectly, or maybe my walls aren't as straight as they should be. either way, we had to add a shim behind it. I do wish they were just slightly smoother. but these are cute and have a nice color. I'm happy with them. I would also recommend using drywall screws and not the ones that come with them. screws provided aren't as good. but the shelves are still nice and sturdy. these are good value for what you're paying. I'm happy.
