When I bought my Z4 from CarJax, I discovered months later the airfilter had an old mouse nest in it. The filter was 1/2 clogged with shredded newspaper and cloth. When I changed to the new filter, I never noticed a difference nor an improvement in fuel mileage.

A manual transmission can be set to "comfort", "sport", and "track" modes simply by the technique and speed at which you shift it; it doesn't need "modes", modes are for manumatics that try to behave like a real 3-pedal manual transmission. If you can money-shift it, it's a manual transmission. "Yeah, but NO ONE puts an automatic trans shift knob on a manual transmission."
