K & N filters were a cheaper alternative to bmw air filters. The price was right and the quality was excellent

The Pro Dry S filter for my BMW 325 is the only way to fly. Getting into the air box although not hard, is still time consuming. So an oil type filter is out of the picture. The quality of the aFe filter is very good. It fits perfectly. Advertised performance gains seem missing. The cost is high in comparison to the oil type aFe or K&N filters. I give this filter a 3 1/2 star rating because of the high cost.
