Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit the Holden VZ and VE series, fitted with an Alloytec 3.6L V6.

 

What are manifold insulators and what do they do?

Manifold insulators are a thermal insulating spacer that mount betweenyour 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!

One of Ann Patchett’s best novels.
Format: Hardcover
“Whistler,” by Ann Patchett, Harper, 320 pages, June 2, 2026. Daphne and Jonathan Fuller are visiting the Metropolitan Museum of Art when Jonathan notices an older man following them. They go up to the next floor and the man is still following them. It turns out he is Eddie Triplett, Daphne’s former stepfather, who was married to her mother for a little more than year when Daphne was nine. They haven’t seen each other in almost 45 years, but he recognizes her. It is a chance meeting. Daphne teaches literature at a private school and Jonathan is a retired hospital administrator. Eddie is an editor at Random House, but he wasn’t at the office this day because of a water main break. Daphne visits her sister, Leda, to tell her about the encounter. Flashback to 1980, when Leda was having an appendectomy, Eddie was driving Daphne to the hospital in a snowstorm and they were in an accident. Daphne had to climb out of a car window and walk for help. After that, her mother divorced Eddie. Of course, there’s more to what happened. This is a wonderful story about adults looking back at the choices they’ve made and the choices that others made for them. It is about the small things that impact our lives and memories of childhood. It is about families, love and bravery. This is one of Ann Patchett’s best novels.

Another amazing book from a talented author
Format: Kindle
This is one of my favorite authors so I knew I would enjoy this book and once again, the characters seemed so real like people I knew personally. I very much enjoyed Daphne and Eddie’s relationship and I loved learning about Eddie and Daphne’s mother’s life together and why things played out the way they did. This book truly shows how people can impact us forever regardless of how long they were in our life. There was so much beauty in this book despite the loss and sadness at times. I received an advance review copy for free, and I am leaving this review voluntarily.

Stunning Storytelling
Format: Kindle
Excellent. I read The Help on a whim all those years ago and was spellbound by the author's ability to weave a complex story across multiple narrators. When I'd heard that her second novel was coming out, I added it to my library wishlist as fast as I could. Then, the second I got word it was available, I couldn't help but immediately dive in... and, because her first novel made such an impression upon me, I had so much trust in the author's ability to deliver a story that I hadn't even bothered to read the blurb. Going in blind into the Calamity Club was a discovery! I was charmed, entertained, amused, and once again, spellbound by Stockett's ability to shift between narrators. One, a somewhat sheltered but very bright and kindhearted woman Birdie. And the other, a charming and very intelligent 11-year-old seemingly orphaned girl, Meg. But beyond this, her ability to weave together a story featuring the fringes of society, giving people -- women, of various walks of life -- a voice in an era where women might have the vote, but are still subjected to a variety of society norms, laws, and double standards, is still very compelling. I adored Meg, and I was so invested in seeing how things would turn out for her. And the strong female cast that Stockett features here only adds to the story's strengths. Having read a few comments here on length, while I agree the story is a little long and the try-fail cycle of getting the underground business off the ground may feel pointless for some, it didn't bother me and only served to showcase the strength of the women. There were so many characters in this book that one could examine closer, from the aching pain of Rory's story to the quiet pain of the accidental loss of someone struggling with emotional struggles and alcoholism to the desperation of destitution, and the lengths one might go just to survive. There's so much within these pages to mine and consider, and I thoroughly enjoyed it. My only critique is that I felt it ended so abruptly! I wanted just one further chapter, a glimpse of Meg's future... Still: an excellent read, and the Acknowledgements/Author's Note on the research involved in this one was one that made me think about how far we've come... and the direction of where we might go in the future.

Format: Kindle
Wonderful book! It’s intriguing, heartfelt and funny as hell. There may be a few loose ends they are too easily wrapped up but honestly, it doesn’t detract from the overall impact of the book. I have to say that the story is enhanced by the Audible version, which is something I rarely say because I usually need to see the words in print. But the two readers of the book are superb and add a lot of depth to the characters. Honestly, if there’s a movie made of this book, I will probably be disappointed in the actors who portray the characters of Birdie and Meg because they won’t be as good as Jenna Lamia and January Lavoy who narrated this book for Audible.

Trying times in Oxford Mississippi in 1933
Format: Kindle
The Calamity Club features a cast of strong women and several weak men. The official charitable women are not charitable and the unofficial ones are courageous and are filled with good will. Stockett weaves a long tale of poverty, desperation, determination and sisterly love. Only two sets of sisters are blood related but those who are not, bond by working together for a common purpose. Stockett serves up humor and pathos in equal measure with a dash or two of realism. Her character development makes The Calamity Club well worth reading Like The Help, a screenplay should be forthcoming.
