I live in Dubai, would de-snorkeling my Cayman S not result in more dust ingress? Thinking mainly of highway cruising with side on desert sand storm we get here...???

The 997 if you look has the same cold snorkel concept, so as long as you replace your air-filter every 6 months I would imagine you'll be fine. How often does the dealership recommend you replace your filter as you live in Dubai?

I dont forsee me needing these anytime in the near future and dont want them to go to waste. It appears that we will be obtaining a Panamera as opposed to another 987 S. Please PM me if you are interested.

Sent you a message.

Butt dynos are highly affected by sensory input (noise, intake and exhaust). Always have been.

Before I would remove mine, I'd what to see what a new air sensor costs. Probably not cheap.

I think engineers most certainly would leave, or rather be told to leave 15hp on the table in order to keep the HP and performance numbers of the Boxster/Cayman comfortably below the 911.

They can do it in software a lot less expensively than by making the restrictor hardware. Not everything can be explained by conspiracy theories.

Well, I agree it's not comething that I can image would be done without a good reason. Can anyone with a 911 (turbo?) tell us for sure weather a similar restrictor is found on its intake?

The plate is there for two reasons:

1- Keep cigarette butts out
2- Minimize intake sound

Therefore, restricting air-flow and great sound...

I looked up the Porsche PET docs for the 987 and 997TT.

On the 987:
987 575 647 01 impact absorber plate (AKA - what we call the restrictor plate)

On the 997TT:
Does not exist it seems according to the diagram. Just the air inlet (outside on body) and the air duct
