Clarification, it's not the PSI, it's the air flow, but I agree, with the CX5, the N/A and turbo use the same air filter, so you'll pull in more debris with the turbo due to the potentially higher air flow (really depends on how you drive).
Jumping on my soapbox.....changing filter too often is actually worse to engine protection than just letting the filter collect some debris. As a dry filter loads with debris, it gets more efficient at filtering the air. Obviously you get to the point that it cannot flow enough air or turbo needs to work extra hard to supply the air, but that takes a lot of debris. So, I wouldn't say you should "change it like toilet paper" as was mentioned previously, just change per the manual. Don't overthink it.
