Meirion1, is this Secondary Air Injection System fitted only to North American Jaguars?
I ask because I don't have this, nor can I see anywhere on my intake for this hose to push on? The only vacuum hose on my intake is the one from the Fuel Rail Pressure Sensor to the inlet? There are no other 'nipples' to take a pipe?

 

Meirion1, save you the trouble of replying, I found the answer on the internet.
It was fitted at the 2006 update and only to North American cars.
