If Maryland requires a OBDII Port connection to pass inspection then you will need to use one, or both of the spacers. I can't tell you if you need one, or both. I'd try two first. Install, then restore your car to OEM tune. Drive the 30-40 miles to make sure the reset is done. If your CE light doesn't come on your good to go. If it does then take one out and repeat...Good luck!
