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!

My Fave Sunscreen
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 6 Ounce (Pack of 2)
I love this sunscreen. I bike ride a lot in the summer and I always bring sunscreen with me because I sweat and need to reapply. If I use a cream, my hands end up wet or greasy and I'm holding the handlbars, etc. So, using a spray is way better for me. I loooooooove the smell of this stuff. It smells of summer! The spray makes it easy to get my back while at the beach and while it's not insanely waterproof, it's certainly water resistant and lasts a long time. I like the SPF 50, because less isn't enough for me. They say going higher than 50 isn't any better, so I stick with 50 as my "go to." Buying the duo, as sold here, makes it a good value. Buying this product at a local drug store would cost twice as much. I easily go through both cans in a single summer.

IT WORKS
Style: SPF 50
I used this on my trip to Jamaica and it worked great. I was in the sun for hours and it kept me from getting any lines. I did reapply after going in the water and when I was feeling really hot. However, I did get burned on the top of my feet as the sand was all over them so I couldn't put sunscreen on them. Lesson learned put lots of sunscreen on your feet prior to arriving to the beach. It does stay on slightly when you go in water. You will see a faint white cast on your skin, but nothing extremely noticeable. Otherwise it rubs in really well and there is no white cast, (only after you go in water will you notice it slightly). If your main purpose is to protect your skin, then this is your friend. It's reef safe and does have safer active ingredients that I feel more comfortable using on my skin. Very happy. I used about 3/4 of the bottle for 3 days of use, this includes reapply applications. So if you have a family you may need to take more than one bottle for a long trip and it's a bit more pricey, but better ingredients typically do cost more.

Bought 2nd time
Style: SPF 30
I am loyal to the Hawaiian Tropic brand because they have a wonderful scent. Not like the typical sunscreen smell, but fragrant and subtle. This sunscreen does keep my skin protected and I use it almost everyday living in sunny Las Vegas. Doesn't leave a white film and blends into my skin. It is matte, doesn't feel oily. I prefer the 30 SPF for daily use. This is my second purchase and just want a smaller size for travel. But I'll just squirt some into an empty travel sized bottle because I enjoy it for my everyday lotion.

One of my favorites because it doesn't sting my eyes
Style: SPF 50
This was my first time purchasing this from Amazon though I've bought this product elsewhere before. This is a sunscreen I come back to because I can use it on my body and it works relatively well on my face as well. It is hydrating and can give a matte-ish looking finish although on my face I'd say it leaves more of a dewy look because I put moisturizer on prior to applying. I've seen a few reviews mention there is pilling when applying to the face and while I've had that happen it's normally only during the day when I reapply. I think that first thing in the morning I don't really have that issue because of the moisturizer I put on before- I let the moisturizer soak in a bit before going in with the sunscreen. My favorite thing about this sunscreen is that it doesn't sting my eyes, I've worn it out on 90+ SoCal heat and it has not stung my eyes- there's been numerous sunscreen I like on my face but don't repurchase because even mid-80"s heat causes them to run and both sting and blur my vision. As for my giving this a 4 rather than a 5 it is because it leaves a mild white cast after I apply it norming and reapplying throughout the day. The mild white cast does eventually go away but it does take some time, though that is the one downsides I am glad that I'm at least not forced to sport a ghost-ish face all day. In all honestly, the cast is only mild when compared to others like the New "Sheer" Bluelizard SPF 50 face lotion, among others. I'm a little jealous of others who say they don't have a white cast at all but different products react differently with different people so I know it might just be a "me thing." Overall this is one of the sheer and non-tinted sunscreens I am happiest with and will repurchase again as needed unless I stumble onto that unicorn 50 broad spectrum SPF, cast free, no eye burning/ irritating, and reasonably priced and sized sunscreen =)
