Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit GMCvehicles fitted with SIDI LLT 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.

Love these books. Better for alcohol markers
Format: Paperback, Format: Paperback
I like these coloring books because of the designs, thw fact that the back page is empty (thinking of bleeding) and the amount of drawings on the book. Meaning, its worth for the money. These are cute. Alcohol markers: these pages are made for this kind of markers. They blend well. Acrylic markers: these are not the best pages for these markers. Need to re-do strokes to get good coverage. Are not porous enough. Meaning, I can see the strokes on these pages; but, in other type of paper, the acrylic markers work better with single strokes. First picture: acrylic marker (see the strokes) Second picture: bleeding on back of paper (alcohol marker) Third picture: alcohol markers (other Coco Who book)

Grab one of these for some relaxing coloring therapy!
Format: Paperback
such an adorable coloring book! I would recommend this for adults who like to color as well as children. Coloring pages are cute, easy pictures to color -nothing complicated. Everything is large enough to color easily. I look forward to sitting down with this coloring book and getting some stress-free time coloring.

Charming Coloring Book — Fun for All Ages
Format: Paperback
This coloring book has quickly become a favorite in our house! The illustrations are adorable and relaxing, making it just as enjoyable for adults as it is for kids. My daughter and I have spent hours coloring together, and it’s been a great way to unwind after school or on quiet weekend afternoons. What I love most is how versatile it feels — the designs range from simple and playful to more detailed, so everyone finds pages that match their mood and skill level. It’s also a fun way to keep little hands engaged without screens. Whether you’re looking for a creative activity to share with your kids or a gentle, artistic escape for yourself, this coloring book delivers plenty of charm and enjoyment. The only reason giving 4 stars is because of the price. Although the book is great, I do not think it is worth almost $10.
