Exclusive to Mace Engineering, here we have our design-registered lower manifold insulators to suit Opelvehicles fitted with Alloytec LP9 Turbo 2.8L 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 and perfect for European Spring
Color: White, Size: Medium
Very nice for travel. They rolled up perfectly and fit easily into my compression bags. Best of all, they didn’t wrinkle after a 14-hour flight. The material is soft and heavy enough for spring weather in Porto. I wore both colors there in April. I got a spot on the brown one, and it came right out. It also dried quickly without leaving a water stain. I probably wouldn’t wear them in Georgia during the summer. The white is more of a cream color, and the brown is a beautiful chocolate brown. The sizing was accurate. I’m 5’6” and 150 lbs, and the medium fits loosely without looking baggy. It also works well worn untucked over pants. I would definitely purchase again.

Great for the price but not perfect
Color: Light Green, Size: Large, Color: Light Green, Size: Large
I have this shirt in two colors. Can’t beat the price! The shirt is a good thickness (the white is NOT see-thru) and fit well. It holds its shape when washed. Looks great with a cardigan or blazer, and it’s very comfy. Not too tight, not too baggy. I took off one star because it pills badly (see pic - this was after wearing only twice). My fabric shaver took care of it easily, thankfully. It’s also hot. The polyester doesn’t breathe. But again, for the price - great option for layering on a less hot day. For sizing, I’m 5’6, about 185, and a 38C bra. The Large fit me perfectly.

Classy t-shirt
Color: Black, Size: Small
I bought one of each color that was under $8. They are soft, lined with silky material, no wrinkles and are appropriate for casual work or looking out together running errands. They are somewhat structured and feel expensive. Best find for summer over anything I’ve found so far. These beat every high end tee shirt by far in quality, fit and price!

Excellent shirt, especially at this price point--a true can't miss!
Color: Grey Blue, Size: Large
I have ordered this shirt in several colors. It is loose, comfortable and washes up perfectly. So far, I haven't had any pilling. It performs like a much more expensive shirt. Because it is loose fitting, it hides a multitude of figure problems. I love these shirts.

My favorite t-shirt EVER!
Color: White, Size: Medium
This is the classiest t-shirt i have ever owned. It is buttery soft but thick so that nothing shows through. Thick doesn't explain it well because it is like silk on your skin. Anyway, I highly recommend such a lovely shirt!
