Having a spare filter makes it much more convenient to clean the one being used without having to wait for it to dry.

Use one on my F350 diesel (factory) and bought aftermarket CAI for use on my F250 gas motor. Replaced filter with one of these and noticed .3 mpg improvement and easier engine "breathing". Believe it will easily pay for itself.
