NG 900/9-3 Cone Filter Intake
There are two intake options. The DIY 3" intake is inexpensive and provides good results. The performance benefits of the commercial cone filter and heat shield kit are minimal. The primary benefits of this over the DIY intake are looks and intake noise.
Purchased from Genuine Saab, direct replacement of stock air filter and box. Kit includes cone filter, 3” steel elbow, ring clamp and heat shield. It does not include bolts to attach the heat shield to the frame and the bolts on the stock air box are not removable. Simple solution is to buy four nuts and bolts from a hardware store.
Initial impressions were good, performance seemed slightly better. This is partly due to the fact that my old filter was rather dirty. It is much louder than the stock air box, even with the 3” intake and drop in K&N. The heat shield was a tight fit and required a bit of work to get it in, but it fits well.
I am planning to add some padding around the edge of the heat shield to better seal it.
Cone Filter Area = 76 in^2 Stock Filter Area = 51 in^2
