Technically it would yield a "slightly" higher CR. (less than .1) Remember it is only a shell & electrode not a solid object.
However the bumping I would be worried about is the piston & the ground electrode.
Plus the fact it disrupts the incoming air charge (flow & swirl) much more sticking that much further into it's path.
