1.2 Clio - inlet manifold bolt snapped

[HFC2197]

Stupidly, while changing rocker cover gasket, I've managed to break an inlet manifold bolt on my 1.2 engine (by failing to use a torque wrench) and it snapped. The car runs perfectly fine apart from a SLIGHTLY rougher idle, which is almost unnoticeable. Should I leave the remains of the bolt in the head, or attempt to remove it? Has anyone had success with left-handed bolt extractors?

Pic attached. Thanks

Can't you just take the inlet off again and turn the bolt out with some pliars?

Possibly, depends if it's sticking out enough above the head. If not I'll have to try something else when I get a chance to remove manifold again
