Three-Stage Intake Manifold N52B25 - 323i

Like I mentioned before for people who didn't believe me, the 323i comes factory with the DISA Actuator.

The Canadian 323i is acutally an Euro 325i with a Three-Stage Intake Manifold.

A simple ECU reflash will get you up to the European Spec 325i performance range.

323i CA 2007+ 2.5 L I6 200 bhp (149 kW; 203 PS) 180 lbft (244 Nm)
325i EUR 20052007 2.5 L I6 218 PS (160 kW; 215 bhp) 250 Nm (184 lbft)

I spoke with a tuning company, and they said that on the Euro 325i they were able to produce figures around 233hp and 206 lb/ft.

On top of that, primary cat removal and retaining the OEM exhaust shows a 15whp gain on top of everything, which is not bad for a engine which is a high-reving 2.5L straight-6.
