Brilliant, thanks just ordered both

looking forward to the weekend already! I have a feeling that the cover gasket may be leaking as I have had a bit of oil in the bottom of one of my plugs, hoping this is causing the misfire under boost, got a bit of a tapping noise when the revs drop suddenly when revving, and also at a certain amount of revs. If this isn't it I'm not sure what it is! Replaced the maf ignition amp all the plugs next is the coil packs.
Thanks for you help muchly appreciated
