Well, I have found a problem, I swapped out the RCM first as you never know your luck, no change there.
So I disconnected the CAI and looked at the throttle body and guess what I found?

Where did it come from, there is one already on the OEM intake, I checked as I thought it must be missing.
It is trapped under the butterfly, I'll have to be careful, I do not want pieces of it in the SC, but maybe there is some already in it.
Looking down stream I found the culprit, the air filter had disintegrated.


Some pieces of the rubber has gone missing in action. I guess the inter cooler has to be inspected for bits of rubber. Anything going through the SC like rubber would be ground to small pieces I am thinking. The Green filter was put in while I cleaned and oiled the K&N one, guess I forgot.
The moral here is to inspect that filter, the oil may help it disintegrate but maybe it is just age that does it.
