325/330 use the same intake rite, so there is absolute no difference for 325 and 330? how bout the year difference, for example will year 02 be different than others or its the same as any others.?

Just so you know, the 325 and 330 ECIS intakes are different......

The only difference on the ECIS is the filter size. The 325 uses a 6 inch filter and 330 uses a 7 inch. I don't know why there is a difference in filter size. The old e36 325/328 used a 9 inch filter! From what I know, depending on the filter diameter, a 6 inch filter will support a car up to 280 HP and a 7 inch is like 340hp. The difference could be the 330 draws more air and requires a larger filter but again the e36 used a 9" so it makes no sense.
