can they really give you better fuel ecenomy as long as you keep
your foot out of it?   2. stephan      stephan Rockstar 4 Years

pump (because that's all it really is). It's pumping air in &
out every minute it's running & the easier the intake path
allows the air to flow in, (or out, look at the exhaust side
too) , the less energy the engine wastes trying to suck the air
through a restrictive intake. But it's like you say, you have to
be able to keep your foot out of it to realize the MPG gains :)
something that's hard for most of us to do at first lol   3.
