On mine a heat shield that does not shroud the filter but is a single wall between the engine and filter would be no use (you cannot seal the filter from the engine bay), as the air temp would equalise out over time, but with a cold air supply to the filter, you negate most of the heating effect, and as i said way up in the bubbles of quotes above, I have had no pre ignition issues.
If there was a problem, then the fogged air box would be the answer, which in itself is a rough type Simota.
I think the only true way out of a heating issue to fit a snorkel like on the MR2 mod, or sit the air filter outside the car like on a Westfield.
to be honest - I think your credibility was shot when you said your set up was "forced induction"
you should maybe stick up some before and after dyno plots for us though, given that bum dyne's count for squat
To be honest my large browed friend, i find it hard to understand any comment you make, perhaps you should add some extra speaker pods to improve your sound stage.
What the F@*K has a dyno got to do with this conversation, we are talking about induction, if you have followed the thread you would have noted that everyone except the extinct here have agreed that power is not gained by changing the induction alone.
(For information, if you adapt the air flow to be pushed in rather than pulled in (ref cold air supply, air scoop, front of car, car forward momentum = air pressure at front) then in my humble opinion this is forced induction, maybe not to the extent of a turbo or a blower, but it is forced induction - credibility restored!)
The discussion has then moved on to heat build up, where the merits of the Simota system have been confirmed as the carbon shroud provides the heat shield and the design allows it to be placed as close to cold air as possible. It has then been discussed, that a single wall heat shield would make no difference as it cannot prevent heat build up over time as it is not sealed.
It was then discussed that the two alternatives to reduce heat are either the fogged air box or a cold air supply. (Simota do not make an M44 version)
Have you managed to keep up?, There is a lot of information on this forum reference the benefits of induction, i suggest you go read them and get an Induction (see what i did there? probably not)
To finish the main problem on open filters and the reason why heat becomes a problem is because people do not spend the extra and fit a cold air supply to the filter. similar to fitting a turbo and not reducing compression, you are going to get problems.
I agree with the earlier post, do you actually own a Z3 or any car for that matter.
You could always check the DVLA again for the answer.
I have the simota now nice but not as obvious.
people often confuse sound with power....... big mistake
or maybe you've found a new way to pass air through solid surfaces that will delight and astound the science world? 
sorry you've lost me - where have I called you any names?
