I had Oil PRL cobra air filter before on my FK7. Car was shaking and idle funky. The K count on my ktuner went from .49 to 1.60. I replaced air filter and it didn’t change anything. I cleaned the MaF sensor even though it I didn’t see any gunk on it and the problem disappeared immediately.
You do need current speed display so u don't get pull over if you are accidentally speeding in front of troopers and cops.
I can understand if u need gears for padel shifter but driving a sticks is a muscle memory thing.
I get you about a small single digit for the Hud. It doesn't hurt to...
I have HPS in mine. I got it on sale back in February. I love it. The installation was super easy and straight forward. Other thing different is the ID bigger than PRL. More pieces to install.
