Back to back wouldn't work. Not enough time for the ECU to learn the new intake and give a proper dyno, nor would it be fair as, all day the temps would change, the engine would have to be cooled down.
It would be easier just to dyno each car with each single intake.
Once the car is moving the ambient air temps where the SRI is located drop significantly (No more hot engine bay) neglecting any advantage that a CAI might have in regards to the MS3. Been there done it, I know. Have fun changing / cleaning your filter for your CAI, this argument isn’t going anywhere.
