Review on 🏎️ Enhance Your BMW (M3) Performance with K&N Cold Air Intake Kit: Boost Horsepower Legally by Committed Schmidt

Had to replace the heavy duty filter. Installation was fairly easy, except the intake manifold was attached to the air intake. It is best to have 2 people for this part. Performance: Better throttle response noticed, it's almost like Sport mode. You can feel good pressure at around 3000 rpm and it pulls hard until the fuel is cut off at 8200 rpm. As for the horsepower gain, I now have a traction control indicator that flashes throughout 1st gear, this was not the case prior to installation. the inlet is growling I live in Az and so far it is not heated. It has good airflow from the bottom and top vents so this shouldn't be a problem while driving.
