Can I ask what's the benefit besides lighter?
Is the inside ported for smoother air flow?

Yes the inside is opened up alot compared to the stocker.

I believe cold air should to be considered more than smoother or more air flow,

while "Renntech" still the same position as stock, then don't see that good benefit with it..!!

*don't take that as GENERAL, just my own opinion..

HP is all about airflow, more air in and out, more power. That is going fast 101.

I'm not sure what you're talking about with cooler air. Renntech and stock both pull air from outside of the engine compartment at front of radiator. That is about as good as you get as far as that is concerned.


I really am baffled that you think two airboxes being in the same position means same outcome? I don't know what to say to that other than, no.

Any idea of being against the direct heat from intake or Exhaust manifold, i'll completely agree with it,

C43/CLK55/E55 box sits right over the top of the intake manifold which get very hot, so where that damn heat is going, as Example of 55K boxes; they are actually running against the side of intake manifold which would appear to be more effective in terms of feeding the motor with cooler intake air..!

*you may don't like the idea, but as i stated; this is my own opinion, no need anyone to follow it or agree with it..

To reduce radiated heat from the manifolds and block, has anyone tried placing gold sheeting under the intake box? Like this stuff which I am using in my Ultima Can-Am build: http://www.nimbusmotorsport.com/Prod...8314&CATID=268

Was curious if there still is a significant separation (and noticeable gains) between a gutted airbox & a Renntech.

I have thought about this as well. I had some data logged files that were lost when I updated my phone, but I have a general idea of temperatures. It'd be interesting to see if, and by how much, temperatures were effected after applying a material. Correct me if I'm wrong, but this wouldn't be removing the heat, but simply averting it away from the box in order to achieve lower intake temps.

Yes, same assumption as me. Reducing airbox temp = better breathing engine.

I have some foil tape (not gold) sitting in the garage and I was planning to give this a try as well. I had some on the old 300ZX race car on its airbox (which hung out over the radiator). I'm guessing that the AMG airbox may be made from polypropylene, which has very low surface energy and that means that things don't like to adhere to it. So you may need to use an adhesion promoter to get the foil to stick. It's on my (long) list of things to do when I have time to work on the 43.

I would love to see some data on this. I don't recall seeing lower IATs with/without airbox when I worked at RT a few years ago.

The airboxes are wet lay-up, similar to fiberglass. They don't have the radical weight benefits you'd get with the baked/autoclave-d sort of dry carbon you might be thinking of. Same goes for CF hoods, roof panels, etc. Often they're not much lighter (or, at all lighter) than aluminum.

+1000000000 anything sitting over the manifold will suck in a lot of heat the compressor intake setups are much superior in comparison.
