Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit Buickvehicles 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!

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.

Great quality and easy to assemble!
Color: Blues, Size: 56 LB, Color: Blues, Size: 56 LB
I’m really happy with this dumbbell set. The stand was very easy to assemble and feels sturdy once put together. The neoprene coating on the weights is comfortable to grip and doesn’t slip, even when your hands get a little sweaty. I also love the colors—they make the set look nice in my workout space. Perfect for home workouts, compact, and easy to move around. Definitely worth it if you’re looking for a practical and stylish weight set!

Happy customer
Color: Black, Size: 32 LB, Color: Black, Size: 32 LB
I recently purchased a set of black dumbbell weights, and I couldn't be happier with my decision! These dumbbells are solid and built to last. The weight material feels durable, and I can tell they're gonna last. These weights are perfect for all my exercises. They come in a range of sizes, allowing me to easily adjust the weight for different muscle groups. I love the sleek black finish! It not only looks stylish in my home gym but also adds a touch of professionalism to my space. The price point is excellent considering the quality and durability of these dumbbells. I've seen similar products at a much higher price, but these offer the same benefits without breaking the bank. Their design makes them easy to grip, and the smooth texture ensures I can maintain my hold even during the sweatiest workouts. Plus, they're compact and easy to store, making them perfect for home use. Overall, these dumbbell weights check all the boxes. I highly recommend them to anyone looking to enhance their fitness journey!

Great Set
Color: Multicolor, Size: 146 LB
This is a great set of dumbbells. I was looking for the weights in this set and I wanted a nice rack to keep them off the floor. So far they feel solid and accurate and are working as expected. The reason for 4 stars and not 5 - The (2) 20 pound dumbbells shipped separate, which was fine...but everything else was in 1 box! That's 106 pounds plus the rack and packaging. The delivery guy struggled and almost dropped it, and then I had to move it from my front door step. How much more could it cost them to ship it in 3 boxes or redistribute it into 2 boxes under 100 pounds? So lucky the box didn't drop and the contents get lost or wrecked. Otherwise it is a great set!
