I would have thought it unlikely that the air filter is the cause of your trouble, but why not put a genuine filter in to be sure? I would think that there's another fault with your car and the new air filter is probably just a coincidence. Let us know if you find a cure

Well so far after changing the air filter and box back to standard, and have placed iridium spark plugs in and a new coilpack as it was misfiring too, an oil change, it seems to be running fine, I'm not holding my breathe though, last but not least the last thing to try is a new maf sensor, it's running between 3-3.2 gr\s is this normal for this car?
