For the 2011 Mazda Mazda6, the low-beam bulb depends on the headlight system. Models with halogen headlights use H7 bulbs, while models with HID headlights use D2S bulbs. The high-beam application is 9005.
Check the headlight type before ordering low-beam replacements, since H7 and D2S bulbs are not interchangeable. The fog light uses an H11 LED bulb.
