"Packaging was great, if not overkill. Fit just like the factory air cleaner and installed in a minute or 2. Could feel a slight increase in power and seemed to help acceleration in higher rpms, nothing major... Wanted an oil-less air filter after hearing about oiled ones possibly messing with the mass air flow sensor. Could be from over oiling. Either way I'm happy with the purchase and feel this is the best oil-less filter I could have bought. Did a lot of research before buying also." —James G from Myrtle Creek, OR bought an aFe Pro-Dry S Air Filters for a 2003 Lexus IS 300.
