I've read that the xkr is sensitive to differences in filter resistances hence batch matched pairs should be purchased, where possible.

​​​​​​I find it slightly hard to believe this is truly a thing though why risk it. Any other opinions/experiences in not getting pair matched?

Does anyone know where I can get pair matched online? Only seen oiled filters coming in pairs and I don't want oiled.

 

I think that's overly pedantic. Two identical filters (same manufacturer / part number) is perfectly adequate.

I would only consider a matched pair of Purdey's as an essential accessory.



A bargain at 89,500 UKP.

Not necessarily, because there may be enough of a flow difference between different lot numbers to trigger a CEL.

That was posted more than 7 years ago in 2013. From the OE filters I've purchased in that time, I know JLR have changed supplier three times since then. May be an ongoing issue or may be resolved.

Just because advice is old, doesn't mean it isn't still valid today!
I have no problem with aftermarket engine air filters. My point is that if those filters are replaced and thereafter you get a CEL, know that the cause could be mismatched filters.

 

Charlton Heston? He gave crappy advice.... he told me to buy Pan American Airline stock. What a flop THAT was.

 

Found some Mann at a good price so I'll have a punt on those. If I get a code, I'll give jag a call.

Odd that nowhere online sells matched pairs though. Does anyone know who manufactures the OE filters? Not bosch is it?

 

Mine had K&N's fitted from previous owner, changed to a new set of the same at 2019 service and took the old ones and cleaned and reoiled, no issues of CEL's

That said I've a spare set of cheapy blueprint filters that would be fitted if I ever encountered an issue

 

Updating my previous responses, the issue of mismatched filters occurred with 4.2L XKR models. It appears that the 5.0L XKR isn't as sensitive because I searched and didn't find anyone who reported that problem.

 

Plus point for the 5lt then?

 

There's only one way to find out. Install two brand new filters in your 5.0L XKR, one from Brand A and the other from Brand B and let us know.

 

The Jaguar part C2P16933 is stamped with "Made in Poland" and the big manufacturer in Poland is Filtron (193/3) whose products do look rather similar.
