I recently ordered 2 engine air filters for my 2010 XK 5.0 I ordered a Mahle LX2671 (2). My car currently has 17,000 miles but I'm not sure if or when the filters were ever changed. I also changed my cabin filter with a Mahle LAK 364 which was a little tight but worked after removing some outside felt. Are the Mahle Engine Air Filters a good choice for our cars? I didn't realize the Jaguar OEM filters at the dealer were only slightly more $10+ each more. I'm going to have my Indy change them for me, and I don't want any fitment issues. I also read somewhere, that some owners experienced a check engine light after changing their filters. Thanks all.

 

The K&N engine filters are pre oiled at the factory and in some cars, can cause the check engine light to come on. The oil apparently messes with the MAF sensors if memory serves. I use Mahle, no issues, no lights. Nothing wrong with OEM either.

 

If XKR engine air filters are not installed as a matched pair, a Check Engine Light can result due to uneven air flows. You don't have that problem with an XK because it has only one engine air filter.

Silly me...... I thought I had 2 engine air filters! With 17,000 miles, I'm probably not even going to bother changing the filter for the present time. Thanks everyone for the info... As always, I'd probably be better off with the original OEM from Jaguar....There is always something (regardless how small) that's slightly different with aftermarket making something difficult. PS... I'm also probably better off holding onto the filter for the future... considering what's going on these days.

 

@Stuart S @bocatrip 5.0ltr XK N/A also has 2 air filters, 1 for each vent. 4.2ltr engine has only 1 filter.

Had them replaced about a month ago. I bought oem ones, one was from 2018, the other was from 2023.

I was also worried about the mismatch but since no supplier had a matching pair in Poland, I just went ahead and installed them.

So far so good.

 

@Brachacz I stand corrected. Thanks.

 

So... I assume that mismatching the two filters is not really an issue? I guess some have and others don't or is the XKR a factor is mismatching?

 

Jag OEM air filters are not made by Jag anyway. Most assuredly made by one of the major manufacturers, perhaps even Mahle. Just like OEM branded oil filters are made by a major.

 

Well I learned something today I guess! I had no idea that the XKR has 2 engine air filters. I replaced my driver's side about a month ago not knowing that I should have bought two and also replaced the passenger side. Just for record, despite doing this I didn't get a code thrown at me. The new filter was Wix brand, part number 49500.

 

Yeah I don't have that worry because I just have the one but I wouldn't hesitate to mix and match. Would buy Wix, Mahle, OEM. Wouldn't buy any filter that's pre-oiled (K&N for example). My two cents and worth about that:-)

 

I also don't buy the K&N oiled filter hype. While K&N filters can provide some measurable HP gain at high RPMs, any gain during normal street driving is entirely psychological. That "benefit" doesn't exceed the cost, IMO. Just my . And that's not worth what it used to be.

 

I just received my 2nd Mahle (Made in Portugal) engine air filter LX2741. I’m planning on holding onto both for future use. I’m clueless as others are to accessibility of parts in general for our cars. I feel it’s premature replacing my air filters after 17,000 miles. I just replaced my cabin filter with a Mahle LAK364 as well as that can’t hurt after 10 years.

 

10 years for a pollen filter is wild 👀

17k miles isn't that premature, however it does matter what conditions the filters were exposed to. A lot of dust, dirt etc will clog the filters faster while superficially mileage would be the same.

 

Went on the Wix website and it didn’t list the 49500 for any Jaguars. I did show the 49381 for the cabin air filter, though. Anyone else use the Wix filter?

 

A6Gator, I used Rock Auto for the purchase, the part number I bought was 49500. Hopefully that helps!

 

Appreciate the response. Changing air filters in an XK is really a PIA, so didn’t want to get half way through.

 

From the Tech Training Manual (of many years ago)

Twin Air Intake System
The AJ40 is the first Jaguar V8 SC engine to use two mass air flow (MAF) sensors to monitor air intake. The use of two sensors allows the engine to cope with the increase in engine air flow while maintaining the service intervals for the filter elements.
The engine air intake and distribution system comprises:

• Two air intakes
• Two air cleaner boxes
• Electronic throttle
• Supercharger
• Two MAF sensors
• Two supercharger charge air coolers
  
  One MAF sensor is fitted at the outlet of each air cleaner box. The intake elbow directs the metered airflow from the throttle body outlet (underside of the throttle body) into the intake of the supercharger. Each sensor provides an input signal to the ECM. If one of the sensors should fail, the ECM will use a model in place of the missing signal. The system will continue to operate, with slightly degraded performance at full load.

 

Thanks for the note. My 2012 is a base 5.0 XK. So, is cleaning the MAF sensors part of swapping out air filters? Seems like this job is growing… Is the MAF sensors something I can spray with Gumout or is this a removal and clean project?

 

ONLY use MAF cleaner! And then there is the debate... to use oiled filters or not. I stay with paper.

 

Yes you remove it to clean. Just get some CRC MaF sensor cleaner. There are good videos on YouTube. Not Jag specific but the process is the same. Leave the car off while doing it or you can throw a code. Don't use a brush, just spray. Let the cleaner air dry. Don't put it back in wet.
