Steve I wonder if you have yet got numbers for the 2 ltr GDI parts you requested (oil filters, air filters, plugs etc). If you have could you please share them here. Have contacted K&N and gave them car details and was advised that they could not 'recommend parts for modified vehicles' obviously Morgan fame has not spread that far. The latest +4 on Demon Tweeks site was filter for 2009 2 litre so 2014 GDI's not referenced there. Mine just passed CT test here in France but official dealer for service miles away in Toulouse and was considering servicing it myself.
