I had to fiddle with the stock settings in my 2020 Impreza Premium to get the response I wanted from the speakers. I’m an audio engineering hobbyist, so I spend a lot of time getting what I can out of speakers without having to upgrade. First of all, I can’t say I’m a fan of the speed sensitive...

I was informed that the K&N cold air intake made for our cars messes with the ECU and the functionality of our cars. My question is does it throw a CEL and does it need a tune after? Also if anyone has had an issue with this please let me know of the issue you had! Thanks in advance
