Rover Sports Register Forum

Hi everybody,
I am new here, even though I have a bought my 1935 Rover 14 HP some years ago. Its now time to change the plugs, but I am not sure, what type I should use.
Can anybody advise?

Here is a link to a discussion we had on the forum some time ago about plugs. Hope this helps

Thank you, I have fitted Brisk L17C, they correspond with those mentioned in the discussion.
