Air filter work questions
Hello all,
This past weekend I decided to go have a look at the air filter. I bought the car at 4800km and am now at 12000km. Car is a 2019 C4S.
Everything went well but then I encountered a clamp I had never seen before. It holds the Y-pipe tubing to the rubber hose down to the intercooler. See photo.
I've delt with worm drive clamps before but the one used by Porsche has tiny teeth that dig into the rubber. I unscrewed the screw but nothing was coming apart.
Is there a special technique to remove these type of clamps?
Also, how are the pipes removed from the Y?
Thank you for any advice.

Simlar concept as other clamps-just loosen the screw and you will need to shift/rotate the pipe to break the seal from the rubber. I would suggest loosening all the clamps on that pipe (throttle body connector, and one on each intercooler pipe). From there, disconnect the throttle body connection and "twist" the pipe to separate it from both intercooler connections. From there remove the pipe completely.

If you have any other photos of the engine air filter, please post them. I’m not sure I have seen the rear of the 991.2 air filter change up close. Thanks in advance.

You'd like picture of the actual air filter or any other pictures of the work to get to the filter?
I've got plenty of pictures and a few videos as I went into it. What I did notice is that a lot of things are different then going into a 991.1. Starting with removing the bumper cover.

The rubber hose gets stuck to the plastic tube. When I changed out my air filter in the 991.2 I had to use a hard plastic prybar type of tool to wedge under the rubber hose to breakout loose.

That was my goal but got stuck at the worm clamp and decided to reassemble and maybe go fo a ride. But 2 friends stopped by to talk about cars and Porsches.
