The ER air intake kit was easy to install because BMW made it simple to remove the stock airbox. By undoing one bolt and lifting it off two grommets, Fred was able to fit the intake in 5min.

02 sensor is transferred to ER intake
Once the sensor was transferred to the ER intake, we were ready for our final dyno with all three components. However, we were surprised to see F30ís horsepower numbers drop by 1hp; while the torque climbed 3 lb-ft and peak boost held 21psi between 4000-5500rpm.

After analysis, we decided the minor dip is within the tolerance of the dyno and canít be felt on the road, whereas the torque gain was noticeable. Whatís more, the intake creates smoother acceleration through the power band, enhancing the previous two additions.
