b/g 182, meg tourer
as everyone knows... disconnect the air feed pipe from the airbox (the one behind the headlight) and you get a nice induction sound is this safe to do? cant see it being too much of a problem. will more debris get to the filter?
i guess it might vary between cars but i've played with the air filter on mine to see what difference running without one/without various hoses attached makes to the performance (none!), the MPG, and noise - and running without that hose connected lost something like 4mpg (according to the OBC) at m'way cruising speeds
it's easy enough to moniter yourself to see how your own car reacts
I don't buy the "worse MPG" claims
All your doing is loosing a small amount of CAF. It's by no means dangerous, but inlet temps may be marginally increased.
If you want real roar- relocate, or get a smaller battery and rig up a cone filter (open IK) with an induction pipe and a heat sheild to protect the cone.
