Exclusive to Mace Engineering, here we have our design-registered lower manifold insulator to suit the Holden VE and VF series, fitted with the SIDI LF1 LFW 3.0L and LFX 3.6L 6 cylinder engines.

 

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 about 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.

 

Key Benefits:

  • (6.35MM – 5%) (12MM – 10%) (25MM – 13%) increase in bottom end torque.
  • Design registered.
  • Reduces charge air temperature resulting in better power consistency and detonation prevention.
  • Power increase with no undesirable side effects.
  • Improved low end torque by increasing runner length.
  • Improved fuel economy.
  • Easy to install.
  • Can be used as a replacement gasket.
  • Reusable.
  • Proven gains at an affordable price.

Coat lover
Size: Large, Color: Black
This coat is warm, stylish, and very well made. The stitching is clean and the fabric feels durable. It’s perfect for layering and works great with jeans or leggings. I love that it keeps me warm without feeling bulky. Great value for the price.

Good quality
Size: Medium, Color: Navy
I gave this as a Christmas present and he loved it. I was worried when I ordered it that the quality might not be that good, but I worried for nothing.

This is more like a long cardigan sweater, than a coat.
Size: Small, Color: #2 Blackandwhite
This is more like a long cardigan sweater, than a coat. It doesn't have much structure & the pocket placement is too high for a coat. That being said, it's very soft & comfortable. As far as sizing goes, the sleeves run a bit long, but the coat, itself, runs a bit tight. I'm 5'10'' and a small fit me, but I wouldn't be able wear anything very thick under it & I'm thin. It's light & machine washable. I almost kept it to wear as a long sweater, but it looks like a coat ,so I sent it back. If you're very thin with long arms and don't mind the pockets being a bit high, then this could be a very stylish piece for you. Otherwise, I would pass.

i would definitely recommend. stick with your regular size or size up for a less slim fit
Size: Small, Color: Black
I usually wear a medium, I ordered a small based on reading the reviews. I am 150lbs 5’4”. this coat fits great for me personally. it’s not bulky, it’s not baggy. it is a slim fit jacket, definitely more on the slender side. when i raise my arms above my head , the sleeves do come up a bit. I would suggest sticking to your normal size or if you want a less slim fit with a tiny bit more room, sizing up wouldn’t be an issue. the coat is super soft and has some weight to it. i would recommend this jacket, it is warm and a nice piece for formal attire.
