Need to replace them and want same or same as factory.

 

Not sure -- the 4.2 I own are Denso's. I've heard mechanics bitch about aftermarket Bosch sensors, but offhand not sure the OEM for the 5.0.

 

Important here..... WHY do you need to replace them? Do you have a misfire, or maybe a CAT efficiency fail?

 

90k miles,no cats and leaded race gas.. They need replacing.

 

I was looking into this a while back:

Down Stream - C2C22679
Bosch 15373
Denso 2344951

Up Stream - C2P8819
Bosch 15375
Denso 2349125

I think I found all of them on Amazon.

 

Thanks.

 

Those numbers were for the 4.2L not sure if they work for the 5.0L

 

no,probably not

 

So, routine maintenance. Got it.
Since No Cats, do you REALLY need the rear (actual O2) sensors? They are only for finding a fault with the cats, and since you don't HAVE cats, why need new? Of course routine maintenance fits that, but they are so pricey!

 

It uses the rear O2s for fueling purposes unlike most cars,,its a Jag of course and if you turn them off it wont pass my Texas smog inspection,
it will show "not ready" even if you tune them out.
Its a Jaaaaaag..

 

No they don't, and these are for the CAT Fault CEL:
But hey, you totally can buy and replace everything. It doesn't hurt my feelings. I've done it myself for other people, but never replaced working ones for myself.
Seriously, I'm not complaining or calling you silly or anything. Others who read this thread in the future may want more information.
Oxygen Sensor Spacers for all vehicles to avoid CEL.

 

Hi htrdlncn,

Your 2011 XKR should have the Denso 1.6 Engine Management System, so your original oxygen sensors were made by Denso. You can look up Denso part numbers here:

Here are the part numbers listed for your car:





Rock Auto usually stocks Denso sensors.

For the F-Type and other mid-2010 models, Jaguar used Bosch EMS and sensors.

Cheers,

Don,

Post #12 above has ....
Never mind, it was just discussed above with time overlaps. YAY for the EDIT function!

 

Don, do you know if the Denso site is using the US years or the UK years?
my 2011 US would be a 2010 UK and those 2 years have different part numbers.
Thanks

 

That's a really good question. The EU site gives different part numbers by VIN:
