Hi everyone ive been trying to iliminate crackling on AM on my cd6000 ive cleaned up the earthing points under the bonnet and also the threaded arial.That leads me to the plugs i,ll be changing them soon which would be best? Its a focus2002 1.6 Zetec se Thanks..

not sure which are the best plugs, just go to a motor factor tell them your reg number and they'll sort you out, I would be inclined to change the plug leads aswell if they've not been changed as they may be starting to weaken hence your radio interferance

Oh didnt think of the leads Thanks Fishpond..
