Im not overly cocerned. Just means air boxes and pcv valves. Not much emmissions for l or a series cars.
Carbon canisters etc won't do much anyway. This is a rubbish law as a fair few stockish large capacity cars will also fail in almost stock form for noise and emissions.

Heard a massarati or m3 or fpv or hsv lately....
Most coomodores and falcons and magnas get a bit smokey too.
