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!

Nice shape, highly polished, 200ml, 5+ stars.
Size: 6.8oz/200ml Silver
Very nice, highly polished with the feel of quality for the price. I'm very much an amateur barista. A trip to Italy inspired me to buy an espresso machine. I gained a whole new respect for coffee in Europe. The pitcher with my machine was too big to copy the Euro style cafe. Small quantities of milk were too shallow to froth properly even when tilting. The barista I watched in Italy was using a small pitcher so I decided to buy the 200ml version. It's a perfect size allowing a small amount of milk to be deep enough to froth. I brought back some roasted Italian coffee beans back to USA and wow! I'm very much a beginner but having fun.

Incredible quality, just buy the right size (I did not)
Color: A Silver, Size: 12 Ounces, Color: A Silver, Size: 12 Ounces
For anyone interested in this product, here’s a quick guide (from a coffee snob) • 12oz (what I got, pictured) - fine for small drinks (standard mug) at home. one drink, and you never plan on using this for any larger drinks • 20oz - the home kitchen sweet spot. if you’re filling a Stanley or Yeti traveler this is probably your size. One caveat, you’ll have no wiggle room and will be maxing your milk froth to the brim. if you like cappuccino’s get the 32oz. • 32oz - this is what’s behind the counter at every coffee shop you’ve ever been to. if you’ve worked a bar shift at Starbucks you’ve held this pitcher a thousand times. If you like a lot of foam (cappuccinos) i would suggest anyone serious about at home use to get this one. I’ve worked in coffee shops since I was like 16 and I still ordered the 12oz like a complete idiot. I posted comparison photos if you want a good laugh. The pitcher is smaller than a regular coffee mug. Not a travel mug, not a big mug, just a normal everyday mug. Bigger than the pitcher. I measured nothing and paid the price. Returning it and ordering the 32oz of the same exact pitcher so that should tell you the quality is legit. Feels exactly like what we used behind the bar, well made, solid, nothing cheap about it. Just bought the wrong size. For anyone also about to make my mistake: the 12oz works if you’re making one small drink at home and that’s it. The 20oz is probably the right call for most people, fills a Stanley or Yeti no problem. The 32oz is the coffee shop size, if you’ve ever worked a bar at Starbucks or anywhere else you’ve used that size a thousand times and it’ll feel right immediately. Great pitcher. Wrong size. My fault entirely.​​​​​​​​​​​​​​​​

Excellent in every respect, regardless of price. Just get the right size for your needs.
Color: A Silver, Size: 12 Ounces
Over time I've accumulated several milk steaming pitchers, a few of which were 3 or 4x the price, and yet I keep coming back to this one. The build quality is surprisingly high, the volume markings are very clearly etched on the inside and easy to read, it has a nice no-drip spout for pouring, and it still looks as good as new after daily use; No sign of wear and tear or staining on the metal even with high heat milk steaming. This is one of those rare low price/high quality products I only rarely run across.

Great for single drinks, high quality
Color: A Silver, Size: 12 Ounces
High quality milk frother pitcher. A bit smaller than I expected but great for making single size drinks. High quality stainless that holds heat well and is easy to clean. Great value for the price for making quick single drinks with your espresso maker
