Engine knock 2019 GT with Ford tune, no codes.

[Marman]

Hi. Since removing the tune, I have only heard this noise when the engine is cold. That is apparently a normal thing for most people. Shortly after that I installed an Injen intake and have not heard this noise anymore except when the engine is cold.

Perfect. I noticed it when it was cold about an hour ago but once engine was warmed up it went away.
