Mini blizzard water to air intercooler kit, from our blizzard range of intercoolers, to suit Holden factory supercharged 6 engines (L67 engines).

It represents exceptional value considering the fact that the recommended retail prices of these intercooler kits are around $1990!

Exclusive to our blizzard range of water to air intercoolers, is their composite thermal resistant housing! What this means this means is that our coolers do a much better job of cooling the air from the supercharger, compared to their aluminium counterparts as the composite housing doesn't absorb anywhere near as much heat from the engine! Not only does this improve outright power, but also significantly reduces heat soak issues over conventional aluminium housings.

The above benefits stem from the fact that our composite material has a thermal conductivity of 0.29 W/m*K as opposed to 150 W/m*K for aluminium. Therefore, our composite material conducts heat 500 times less than Aluminium!


To see the difference between aluminium and our thermal composite material, check out our intercooler test video clip below.

With the installation our mini blizzard intercooler, it allows you to drop from a 3.4 to either a 3.25 or 3.2 inch pulley, on a virtually stock car and all without the need of an expensive tune*. In addition, car idle and drivability remain unchanged even with the factory tune!

You can run an even smaller pulley for higher boost, but then you'll most likely require a custom tune.

By dropping down in pulley size from 3.4 to 3.2 and the inclusion of our water to air cooler kit, gains of around 30hp are common. Higher horsepower gains can be achieved by further reducing pulley size.

To give you an example in regards to what our mini blizzard intercooler is capable of, shown below is a dyno graph of our cooler in action.

The only mods that this car had to achieve these results are as follows:

  • MACE mini blizzard intercooler kit
  • MACE 1.9 ratio rockers
  • MACE 16psi pulley
  • MACE Cold air replacement air box kit
  • Twin 2 1/2 exhaust cat back exhaust system, no extractors or hi-flow cats

The mini only raises the supercharger a mere 25mm so it will easily fit under the bonnet of your Commodore, without having to modify your air-box ducting, coil pack or bonnet. In many cases you can still retain your strut tower brace (subject to brace type) in your Commodore with the installation of our mini blizzard intercooler.

Shown below are a couple of pics of a customer's mini blizzard installation.


Our complete cooler kit includes the following:

  • 3 piece core, with our exclusive composite thermal resistant housing!
  • Full size front mount radiator (600X330X50mm)
  • Front mount radiator brackets
  • Quality Flojet pump
  • Injector spaces and clips
  • Longer supercharger bolts
  • All hoses including fill kit
  • All hose clamps, fittings
  • All installation accessories
  • Fitting instructions

This kit comes complete with everything you need except for engine coolant (genuine Holden coolant required) and a new supercharger belt.

We also offer precision CNC porting of the supercharger and lower intake manifold at extra cost.

*As every car is different, we always recommend that you get your intercooler kit installed by a professional or at least inspected by one, to determine as to whether or not your car needs a tune

Tight at first, but they stretch after a short time...feel perfect after the first week!
Size: 9.5-10.5, Color: Charcoal Faux Fur
I love them! My first impression was "oooh, this is too tight". I wear a size 10 shoe and honestly, the 9.5-10.5 felt tight when I first tried it. Without socks it felt okay, with socks my toes were right at the top. But I loved the style so much I decided to give it a chance - I am SO glad I did!!! They do stretch and give, so don't expect it to be tight forever. I have had them a week or so, wearing each day (I WFH) and they feel really nice. I also live in the mountains, we just had our first winter storm, and these slippers are nice and toasty. Exactly what I needed. The memory foam is plush, though I have had other slippers with it and I know it will squash down over time. Right now, it is a nice feeling as I walk around the house. They are super cute looking, wearing leggings allows me to feel like I am stylish even while still wearing my sleep thermals. YAY!

favorite slipper ever
Size: 8-9, Color: Charcoal Faux Fur
I love these slippers. They look great with pants tucked in. Incredibly warm and comfortable. I wear them almost every day. Fit is true to size. They stay up but are not tight at all. On top of that I get compliments on them. Highly recommend.

Favorite Slippers Of All Time
Size: 6.5-7.5, Color: Charcoal Faux Fur
ETA 7/2024: So I ended up buying a size 5-6. They fit better around the top and sides of my foot but the sole is a bit small. The 6.5-7.5 sole fits better but the material around the top and sides is roomy so it bunches up. Sigh. I still love these slippers but the fit is frustrating. I'm obsessed with these slipper boots! They are so cute and comfy. They look especially good with leggings but I also like that I can tuck other types of pajama pants into them. I'm short and have to fold the waist of most pajama pants so they're not super long on me, but with these boot slippers on I don't have to worry about my pant bottoms dragging on the floor since I can just tuck them in. I like that they have rubber soles. I love the look of the faux fur but not sure how easy they will be to wash because of it. I wear a 7 or 7.5 and I got the 6.5-7.5 size. Even with thick socks on they are roomy. Because they are house shoes it doesn't matter much but I probably could've sized down. I like the way they look so much I might buy a size down and use that pair for wearing outside of my house. Some other reviews said they have a strong smell but mine did not.

Cozy warm, overall a good slipper!
I ordered a size Medium and I normally wear a women's size 8 US / 39 EUR and they fit well. According to the box, a Medium in Acorn sizing is Women's 6.5 - 7.5, but I do think these run a little large which is why I went with the Medium vs. Large. The boot part fits well, not too snug or too loose, and it stays up if it has something to adhere to (like over pants), otherwise it would slide down my bare leg. I am super sensitive to scratchiness lol, so I keep the boot part over pants because it is a little scratchy to me. These slippers are nice and cozy, so they keep my feet / ankles warm. The footbed provides a nice cushion and the soles/suede guards are strong but without making you feel like you are wearing actual shoes / boots. I have noticed that the footbed does not have a lot of rebound so there are definitely impressions of my toes inside... which means no one else will want to wear them... haha! I've also noticed the seams seem prominent on the inside, I wish they were a less noticeable, but that is just one of my hangups. So, the only reason I am giving a 4 instead of 5 is the inside is not as soft as I'd like and the seam problem. Regardless, I wear these all the time at home (which is where most of us all are right now) and I am happy with them overall. Oh, and I got the Buffalo Check pattern and it's super cute and fun!

Soft, Warm and Cozy
I have no idea how these stay up, probably magic. I'm tall so it's challenging to find boot style slippers that are long enough. If support or thick soles aren't an issue, these are the best I've ever found! My ankles and calves have never BEEN so warm; these are my go-to's in the evening. They're easier to walk in with socks but, without, they're floppy and loose. I'd hesitate to size down because it's more the lack of structure in the foot, not length. They wash well (air dry); still soft, warm and cozy. Inserts could probably be added to help with support. I tried them because I found them at a fantastic sale price but I'm buying another pair now, for winter. I'm a slipper person and I definitely notice the quality of materials in Acorns, when I compare them with other slippers.
