Part # from GM site 84520923. Could not find answers to the questions about this Performance part from GM. So I am paying back to this forum with an unboxing of the filter to answer some of the questions.
- Is it a disposable filter?
- How often do you change it?
- Do you need to tune the truck to take advantage of this filter?
- Are there any improvement (subjectively by feel and by mileage)?
- Will it improve anything including idle smoothness?
- Slightest change to the sound of the intake?
