K&N 57-1002 - Cold Air Intake for E46 323i 325i 328i — Overview
This is K&N's cold air intake kit for early E46 six-cylinder cars, replacing the stock airbox with a higher-flow intake tube and reusable cone filter. Fitment is aimed at 1999-2005 E46 models including 323i, 323Ci, 325i, 325Ci, 325Xi, 328i, and 328Ci. If your factory airbox is cracked, tired, or you want a little more intake sound without piecing together a custom setup, this is the straightforward off-the-shelf option.
I'd pick this over a generic short ram if you want a known-brand kit made specifically for these E46 chassis and don't want to sort out couplers and brackets yourself. It makes the most sense on a street car where you want a washable filter and cleaner engine bay fitment, not just noise. As with most intakes on naturally aspirated M52TU and M54-era cars, expect the main change to be sound and throttle response feel more than a night-and-day power jump. Check your exact model before ordering, especially if you're dealing with year-to-year intake routing differences or a 325Xi engine bay.
