MGTF - EPA requirements 10.02.10 All MGTF models are equipped with on board diagnostics thus the car is likely already EPA compliant. Older MGF models are mostly not OBD II equipped and thus are ineligible for importation since post 1996 models must be OBD II equipped. This table compares Euro vs. Fed emissions standards, or at least attempts to. The Federal standards are very confusing by comparison with Europe. Since 2002 through 2005 model year MGTF's are Euro 3 compliant it can be seen that they are equal to Federal for hydrocarbons, better for Oxides of Nitrogen and only slightly worse on carbon monoxide assuming that the TF is actually at the Euro 3 limit for CO which it is likely not.
