I have a 2007 XJR that threw a code for running lean. My independent mechanic ran a smoke test and identified a leak but is having trouble finding the part.
I need a supercharger intake duct. I don't have the part number but I am attaching the picture. If anyone could steer me towards one I would be grateful.
Thanks,

Lot's of advantages over a stock intake tube.

 

Hi 2ndxk8,

If you don't have the Jaguar Electronic Parts Catalog, you can download and install it on your computer from this thread:

It took me two tries to get it properly installed, but Jim Lombardi has provided very clear instructions - be sure to THANK him for his hard work making the EPC available. You won't know how you ever lived without EPC once you have it on your computer.

Regarding that intake duct, it is part number C2C16487 for cars up to VIN G35103, and part number XR849656 from VIN G35104.

Jaguarmerriamparts.com has both of the above part numbers listed at the discounted price of $80.58:

But as MoscowLeaper has pointed out, you might want to consider applying that $80 to Caldoofy's Stage 1 intake, which is beautiful to look at and eliminates the power-robbing Helmholtz resonators that were added to the stock intake to reduce noise.

Cheers,

Also check your exhaust side (manifold bolts and flange)
I recently had a lean condition caused by a loose bolt on the exhaust flange

All it needed was a 1/4 turn on each bolt to cure a +15 LTFT at idle
