My GDI passed the MoT today with the slightly modified air intake system and K&N filter. But the Lambda was on the rich side, and the exhaust tailpipes, (which have been clean since having the AR flash) were sooty after Scotland, so I may refit the standard filter and see what happens.
I may also meddle a bit more by removing the long ducting pipe and see if I can get the air in through the side louvres..........
