I think I remember squeezing it by hand, and then wriggling it side to side gently until it came out.

My notes have this: "Remove the AOS tube from the intake just after the throttle body. To do that you squeeze the plastic ring on the serrated parts and slide it off. Even after releasing the clip it still has to slide a decent little amount before it comes off. " until I squeezed the serrated part I had no success..

Yes, squeezing at the serrated side is the consensus. I'll try again with pliers, maybe it's just frozen; I was able to replace the airfilter and took K&N and threw it away...too much gunk; used MANN filter; next time I'll also clean the MAF since I know more about it now...all in all I hope to improve HP (slightly) and mileage.

Cheers!
