The E90 330i had the highest horsepower out of the N52 powered vehicles. The reason for this was while the 128i, 325i, 328i, 525i and 528i received a single stage manifold, the 330i was gifted a 3-stage manifold.
A 3-stage manifold consisted of 2 DISA valves that would divert air to the cylinders that needed it. With more air going to the appropriate cylinders and fuel adjustments by the ECU, this valve system helps extract the most power from the N52.
Luckily this amazing manifold bolts on to any version of the N52 and, after a flash of the ECU, can give you up to 42hp!
Kit includes:
To add even more power purchase the N52 Euro Air box, ES#2072577.
Note: A reflash of the ECU is recommended to maximize gains from this intake. We proudly offer Turner Motorsport software, a leading tuner for this application.
