Question for those who installed a k&n "cold air intake"

[1qazwsx4]

Hi all, I actually have a Holden zb commodore which is the same car but unfortunately due to all the hate around these "Holdens" there isn't much info around. Lucky for me I came across this forum shortly after purchasing the car which as it turns out is almost the same car with a different badge!

I digress... I need some help removing the fitting on the OEM air intake pipe for the PCV valves pipe. I have tried using a fuel disconnection line tool but it doesn't seem to do anything or maybe I'm using it wrong so any info is greatly appreciated! Please see attached pic for the part

To anyone who's brought a CAI, have you noticed any loss or improvement in low end torque? To be honest my reason for installing an intake is because I love induction sounds 😁

Well the suction sound is the only gain you'll see...hear.
Good Buick Forum on FB with CAI swaps.

Yeah that seems to be the case haha. Truth be told I don't use Facebook but if I have no joy I guess I'll have to make an account. Fingers crossed a member here might have some advice, cheers though
