I agree with Leon. The only thing I can see with this is that the sides
are open and that must do something to the air flow, into or out of the
engine area. If you put a "lip" on the rear of the plastic unit, it
would suck air "out" from around the engine, but where would the air
come from to replace it ? ALSO , under my 2003, there is a plastic 1
inch "lip" fwd of the start of the Alum. underpan, that I would guess
that Mazda uses to spoil the air flow under the car. I think I will just
need to wait a while for good weather to see what, if anything this
thing will do. :-)
I must admitttt , I bought it for show as part of my engine bay clean up
:-) If I run over someone, they can look up and say " Gee, look at thet
nice under plate ! " :-)
