I think you have to also look at the intent of the rule(s). From that perspective I dont think it's legal.

I concur. In my opinion the intent of the reg is to allow opening up of the restrictive stock air filter systems while avoiding allowances of things like ram air, cowl induction, and cold air intakes. We subsequently opened that further by allowing anything upstream of the throttle body/MAF/etc.
On the other hand, all air comes from outside the engine compartment, and it has to get in there somehow. We're seeing cold air boxes and radiant and convective heat shields around air filters and intake tubes to minimize the heating effects of the engine compartment.
With that in mind, how does this fit into that mindset? Is it incremental, and if so, within the boundaries of the intent? Or is it revolutionary to the point of being extra-compliant?
I dunno, that's why I'm asking. But at this point, ignoring the value of it, I'm thinking if you trim back the upper edge of the rectangular section such that it is at or behind the vertical plane of the aft edge of the radiator then you're compliant.

P.S., Mr Original Asker, please note that nothing decided on this board even begins to imply what answers you'd get during a protest and/or appeal. This is the Internet and these opinions are worth exactly what that implies...
Mr. Original Asker: It this were to be protested, I'd honestly flip a coin on what the results were. Would most likely just depend upon who happens to be making the decisions, whether they are having a good day or not, among other risky variables.
Nothing wrong with bringing it up for discussion, that's for sure.

We tried one to baseline from a HP and an air-intake temp perspective. We built a better one by V.3 and V.4. (by my definition - torque curve)
As to the plastic over in front of the radiator, I kept mine. It actually keeps better air into the radiator. Back in the day, the 1.6 SM guys were adding the 1.8 piece IIRC to improve cooling. It might be specifically allowed in SM.
Just to debate the definition of the Engine Bay/Compartment .
Where would the radiator be located, or described as being located, if it's not the considered the engine compartment ? I would think anywhere under the hood, and aft of the grill , would be considered as engine bay . Plus, I believe in the definition that Greg supplied, makes no reference to for or aft of the radiator being a boundary for the engine compartment.

Agreed, these do matter for cooling. Dave, look around online, some of the Miata aftermarket places have the factory pieces availabe (gomiata I think?). I just put an NRG aluminum panel on my SU car becauase bling matters... (and it was the same price as the factory piece, and I don't have rules to live by)
