2013 Stock Air Filter is Different.

I bought all these little mods, like the drop in MS Air Filter, and noticed the MY '13 (maybe '12s or '11s) has a new style of stock air filter unlike the white gauze / big pleated like version in the '08s.

Does anyone think the new filter (yellowish, with many thin deep pleats) might not be as restrictive than as the old '08 stock air filter and might be as good as the modified aftermarket filters?

I installed the MS Filter recently and maybe it's a placebo effect, but the stock filter's induction sound / tone seem to be more aggressive and I didn't get the feeling the MS Filter made the car rev any easier than stock.
