I always rated K&N, but TBH I had a Green in the Scoob when it ran the OE Airbox.
That flowed a lot better than my previous JDM STi paper filter, as the Injector duty shot up by about 4% to cope with the extra airflow.
The K&N in the K1 was new and was sealed in the box. The plastic bag it was in did have some oil in the corner.
ITG used to be quite bad for Scoobs as they would pool oil in the corner of the airbox. I think it was these that started the whole MAF killing rumour, although the MAF's are pretty fragile anyway.
