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

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.

An adorable romcom
Format: Kindle
Miranda Macleod and TB Markinson are like the most awesome author duo for sapphic romcoms. Even though they publish really good books individually, when they come together it’s like magic and in “Two of a Kind” they’ve done it again. Maise’s dream is to be able to finally complete her undergrad degree, but that requires money which means she’s stuck in her not so great job. A conference in Las Vegas provides an opportunity to let loose a little when she encounters Drew a charmingly uber confident rancher from Wyoming. But things may have gotten a little more loose than expected when she awakens in the cold harsh morning light. 👀 When the scene is Las Vegas you know the crazy is going to happen, and the storyline doesn’t disappoint. From an intolerance for drinking, helpful cocktail waitresses 😆, pink Cadillacs to the infamous drunken phone call I snort laughed my way through the shenanigans the two MCs get up to. The funnies continue as the scene shifts to home ground, but at the same time is able to weave in complex issues like trust, abandonment, imposter syndrome which gives the narrative some nice depth. The side characters were really nicely done too, providing some of funniest lines and serve as key catalysts for some interesting plot twists. I enjoyed this book immensely and was quite sad it had to end. This author duo is now firmly on my favorite list and I’ll probably read anything published by them. 🥰

One wild night you can't remember brings bad choices to the surface- only in Vegas it's a future.
Format: Kindle
I recieved an ARC copy of this book and was delighted with all the feels. A crazy meet in Vegas and one wild night changes so many lives. Drew carries the weight of so much and trusts no one. Relationships are not her strong trait. A Wyoming ranch girl at a rodeo trying to win a contest to save the ranch. She meets Maisie who is a straight girl that catches her hatwhen it flies off Drew's head. Sparks fly and a connection is felt. They bump into each other couple more times and end time in Vegas with one forgotten wild night. I rode a wonderful bunch of feels with this book. I yelled more than once at these characters who clearly cared for each other but could not get out of their own way. So stubborn and full of false bravado I just want them to share thoughts. It was a delicate balance to navigate the mine field which was their past and the surprise that is their future. The best part of the story was watching how love was changing everyone on the ranch. They give new meaning to running away from your feelings. It was a sweet, often funny and challenging romance. I was curious how or if they would find ways to share feelings. It kept me turning pages just to see what was next. I really enjoyed the characters and the ranch life. A good stranger to lover and then get to know you story.

Cute
Format: Kindle
I enjoyed this story much more than I expected to. Maisie and Drew couldn’t be more different in many ways but they make a good pair. Both women are stubborn and determined and they butt heads more than once but that is ultimately what makes them work. This is a good sapphic story and is worth a read.

Everything
Format: Kindle
TB Markinson + Miranda MacLeod = winning combination. This book was everything I needed. To be fair, having read their previous collaborations, as soon as I saw this book I hit "buy" without even paying much attention to the blurb. I was not disappointed. When I eventually got around to reading the blurb (post-purchase) I was even more excited to read it. The storyline was great, the story well-written, the characters quite likeable and relatable and all in all a great book. I went through all the feels with this: there were parts that made me laugh, parts where I had to put it down because I really wanted to shake the characters, parts where I went "awww" and couldn't hold back a tear. So, long story short, read this book, you won't regret it
