What is the overall opinion on aftermarket air filters?




What are your opinions on something like AFE dry filters in the E55?

Also, can someone school me on the function of the charcoal filter and how necessary it is.
Thank you!

I had been tempted to drop some k&n's in for a while but been talked out of it - by myself the second time! Did a little research and sure enough the oem filter isn't a bottleneck at all. To my reasoning hi-flow filters would only be allowing larger particles - hence more contaminants through? The throttle body is the first place to clear her throat so the beast can breathe easy. A little more expensive than a couple of filters but I guess you get what you pay for...
