You should do a search on Benzsport " Intake Heat Spacer" or something close.
I machined a phenolitic heat spacer to go between the intake manifold and the cylinder head. Plus I put a thermal blanket under the manifold and the block and wrapped the intake air tube.
Reduced the intake temps by 30 degrees.
Lots of good pics on Benzsport and this mod was good for like 10Hp plus, based on the strong Seat of Pants Accel.

The phenolic spacer that I made was 3/8 inch thick and was made out of a plastic called phenolic G-10. This material is stable up to temps of 600 degrees F and is very machinable.
Phenolic's are also very good insulators. I machined the spacer to match the manifold to head gasket. And I kept the thickness to 3/8 inch due to not wanting to move the injectors too far and mess up the fuel spray. And based on other experience I was pretty sure 3/8 inch would provide good insulating properties.
If someone here can post the pics I can send them to your Email address.

Although I made the spacers shown above the company below is willing to make the spacers for Mercedes as shown below.

Jeff,
Although we do not currently offer any spacers for Mercedes, we are always open to new insulator applications. We generally request 20 firm commitments prior to the design, prototyping, and production of a new performance part, although we sometimes make exceptions. Pricing for a set, including intake manifold and throttle body insulators along with necessary hardware such as lengthened studs, etc. would be in the $100
range.
Please assess the interest for your group, and let us know.
Best regards,
Sean Morgan

The spacer is an insulator and keeps engine heat out of the intake manifold.
With cooler intake air you get denser air into the cylinder head and this allows the motor to make more power.
See Outlaw Engr. website for some good info and dyno data.

That sounds good, but what all will be shielded exactly? Is it going to cover the intake manifold so heat doesn't rise to the airbox? I've already done the heat shielding with the thermotec products. So would the insulator help on top of that???

Air is a very poor conductor of heat so putting the Thermotec reflective tape on the bottom of the manifold helps but not a bunch.
The spacers separate the metal parts which are very good conductors of heat. I can take my infared temp meter and measure temps at the cylinder head interface at 200 degrees F and just just on the other side of the spacer at 90 degree F.
When I stop from a hard drive I can put my hand on the intake manifold because it is only 80 to 90 degrees or less. Try that on your car.

Ok gotcha..... now I understand what it is shielding from.... I thought that it was supposed to shield the air box(plastic) from the engine block.... but you are insulating the intake manifold(metal) from the engine block. Cool..... how long would it take to install it?

Has anyone tried wrapping the exhaust manifold with some of the Thermo-Tech product? Does this really help increase exhaust flow or is that not the weak link in the exhaust chain? In addition to the heat reflecting tape on the intake side would this, in theory, make for an increase in hp?

Wow, it's 2005 already? 
Anyway, I perused quite a few SAE articles regarding intake temperatures and their effect on different engine performance and found an interesting standard: By using the SAE correction factor "B" for temperature's effect on horsepower, we see that the correction factor for temperature is approximately 1% per ten degrees. That is, you get a 1% increase in horsepower for each 10 degrees you lower the temperature of the incoming air into your filter.
So, if you effectively lower your intake temps by 10 degrees with the heat shield, you can free up 1% HP...and in my case for my CLK430, that's about 2 HP. Not really the 10-15 you guys are hoping for.
However, when comparing the extremes of winter and summer weather, say 10F vs. 80F and using the 10degree/1% power gain correction factor equation, in my 430's case: 80F-10F = 70 * .10 = 7% power increase for a 275hp car which is somewhere around a 20 horsepower difference between the extreme summer and extreme winter case, then I guess cold air should be taken seriously.
