Just after some advise on changing the air filter on the mk1 golf. I want to remove the original air box and put in something like a k&n round filter or pipe across system. I noticed there is a small hose off the bottom of the box I think it's to one of the pumps? But anyways I take it ill need to put a t piece in after the filter before the carb to re instate that. The other hose is cool air to the cab I take it.

Or to save all the hassle will I get the same result dropping a panel k&n panel filter in the original box?
Just looking to make her sound a bit more beefy/ something to do!! As if there isn't enough!
Thanks all!!
