That’s good news then, one less job to do!
In the Fords the 2.0 MZR (I think mx5 is the LF-VE version) engine has swirl flaps/tumble flaps. They break apart and kill the engine so I assumed the MX5 with the same engine had the same issues but the inlet must be that bit different.
I was going to be disappointed in Mazda if they allowed such a design but seems it was implemented by Ford.
This is the ford inlet for the same 2.0 4cylinder engine that is in the MX5 NC.
