2012 535i knocking

I bought a 2012 535i in March. It has 50k miles. It started making a knocking noise that was very occasional. I assumed lifters since it was cold. I added top end oil additive for lifter tick and noise was less. Now itís June and the noise has gotten progressively more common. I can hear it inside the cab and outside. Sounds like itís coming from down below where the air intake goes into the motor. Itís most noticeable when idling at a stopped position. I hear it between 500-1200 rpm. Knocking becomes more rapid as RPm Increases. Oil change is not due for another 3000 miles. Level is good. Pressure is lower end of normal. Please help!

Big difference between a tick and a knock.
The latter is not good news.

Knocking that follows RPM is not good, especially with oil observations.
