Good-bye to a good deal of throttle hesitation on my Z4. Running some other stuff through my recently-purchased used car's fuel system (to get it back in shape, too); but the added air flow vs. the brand new OEM filter is performance-obvious (a good buy). I really like the fact I do not have to re-oil the high-end aFe Pro-Dry air filter, which itself isn't difficult ... just one less thing I have to do.
