i own a mk4 1.8 sri 5 door.
at the moment i have a full stainless exhust , race tube and a inducion kit fitted.
would i be better of putting the old air box back on or getting a 1.9cdi one for it with a vectra c pipe and a uprated air filter?
if so whats best panel filter to use?
or keep it as it is?
it sounds realy nice but buy the back box it looks like its running rich or over fueling.
