Right, is this the correct code: VW PART NUMBER 1HO 129 607D
And is this how the 16v ABF Air Filter Box looks like?

I only ask as ive bought one off ebay to do the drilled airbox mod on and obviously re-fit ... I never had an original airbox in my car, bought mine with a K&N which I added a Heat Shield and Cold Air Feed too ... and now I fancy fitting some lower fog lights, which means the cold air feed must go, so need to sell the K&N/Heatshield/Air feed and fit an original airbox.
What other bits are needed? Obviously the MAF and Piping is still in my car as the K&N's fitted at the end of it ... but anything else missing or required?
