Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit Chevroletvehicles fitted with SIDI 3.0L 3.6L V6 engines.

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 lookhereand 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.

BEST lip sunscreen I have ever used
Size: Pack of 1
best lip sunscreen I have ever used. Currently in/on Curaçao and no burn! Was out all day yesterday in the sun and this stick was only reapplied 3 times between 8am and 4pm. Reef safe too, that is important to me!

Great sunscreen
Size: Pack of 1
Love it! Not greasy, rubs in well, & doesn't smell. Doesn't leave the typical white sheen if you blend in well. Great to add foundation over. Ingredients are less chemicaly than other products.

Good protection, water resistant
Size: Pack of 1
I love their products. This is no exception. Used it recently in the Caribbean and Florida. Did a great job of protecting my lips and also seemed to have some resistance to washing off when I was swimming or snorkeling.

This lip balm has worked well for me overall
Size: Pack of 1
This lip balm has worked well for me overall. It does what I want from an SPF lip balm and I have not had any major complaints using it. The only minor downside is that it is a little soft, so when you first start using a tube you may notice a few small chunks on your lips. That has not been a big enough issue to bother me much, but it is worth mentioning. Aside from that, it has been a good product and I would keep using it.
