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!

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.

Received giftcard money to replace my plan-protected malfunctioning motherboard
I've been subscribing to the Asurion protection plan for a while. Recently, an Asus Prime PC motherboard I had bought a few months ago on Amazon stopped working well. I ended up considering filing a claim with Asurion to see if they would either fix/replace it or issue the purchase price money, so I could buy the failed electronics replacement component again for my custom-built PC. I went to the protection plan's website and started the claim filing process but couldn't find the category my failed component would be under in order to select it from the drop-down list. I ended up messaging the live customer service. The chat messaging was somewhat slow, the agent told me they were experiencing some communication delays throughout their systems. Ultimately, the agent was very kind and understanding, and completed the claim filing process for me on her side by asking me to provide the necessary info such as the item's product name, date of purchase, price before taxes, etc. I received a printable UPS shipping label in the email, printed it, and returned the item in the mail. Approximately 2 days later, I received an Amazon giftcard code in the email with the dollar amount equal to the item's price before the sales tax. Then I redeemed the giftcard code on the Amazon page and proceeded to apply the giftcard money to my next purchase of a replacement Asus prime motherboard, and it all worked out successfully. Therefore, I had no issues with the protection plan service and recommend it to others.

Fast and easy but I dont trust the process to be fully automated.
The process was very smooth and fairly quick. The only challenge I had was that the CLAIM status showed complete but I had to manually go look up the status. There was no email or notification it was closed. After manually checking the status, I called customer support and they said since I called in, they would process the payout. I wonder if I didnt call in if they would have processed it? Also, the phone rep said they would issue me a amazon egift card but then the next day I received a email saying they mailed out the payout. Very poor communication but so far the process was easy and fast.

Nice functional printer at a low price-point
Style: WF-3820
At this price-point, the WF-3820 is a winner for a home printer with not much printing volume. It prints well. It was easy to set up the printer and wireless printing from a couple of computers. It uses ink cartridges. While Epson goes to great lengths to advertise/tout its cartridge-free printer models, if you don't print a lot this unit will do fine for you. Did I mention that it's relatively cheap? Has a fax function, but I don't have a landline anymore. It is a bit tall, and you have to open the scanner to access the ink cartridges; so beware if you're putting it in a cabinet or shelf without some decent head room.

Good Printer
Style: WF-3820
Given the 'not so good' reviews, I was a little apprehensive to buy this printer at first. This replaces a WF3620, in which I was very happy with its performance. But the print head began to print only Yellow and Black, and several attempts to 'unclog' the Cyan and Magenta nossles proved unsuccessful. But, I am very happy with the WF3820 - both with the price and the performance. It is faster and the graphics are clear and sharp. The 'jury' is still out on how much toner it uses, but suspect it is around the same as with the WF3620. If so, then I will retain my 5 Star rating.

Good printer ... Until Epson bricked it with Firmware
Style: WF-3820
Bought this as a replacement for a small office HP that died on us. It is a good machine. Nice features at a reasonable cost. Good color, full duplex, excellent scanning, and reasonable speed. The drivers are fairly crappy in that they constantly want to update and are poorly written and appear to send too much data home. (max out two cores on a modern i7 for a tiny printer driver update.) Overall a good machine and excellent for the price. Epson ink is ridiculously priced so went with high quality refurbished ink cartridges. Worked great at a good price. Fast forward to July 2022. Epson pushes firmware update for "performance, stability, and security updates" that seems harmless. Who doesn't install newer firmware when it is offered? After the firmware update the printer claimed that the ink cartridges were faulty and refused to function. Turns out that the printer is now a brick until I buy genuine Epson ink refills at an exorbitant price. Turns out the company has had a number of class actions against them in the past for this very shady practice. Time to write up some copy for social media and contact a lawyer. It should be illegal to remove capabilities from a product that has been bought and paid for and working for months. Certainly I will never buy another Epson product and neither will anyone at my company.
