Hey gang,

New Jag owner here and doing some basic maintenance, namely tracking down the P171&P174 DTCs.
First things first, I notice right away that the air filter needs replacing. I purchase a cheap Purolator as according to the lookups online, but it doesn't fit 100%. I had to push down almost too hard to get the filter box back together.

Now, I see several posts about this Visteon system? Should I be looking for a different filter?

(And yes, I am very new to this car, 7 days purchased)

P.S. it's a 2003 S-Type V6 3.0 if the sig isn't working yet.

 

Huh, well, Google knows all, I suppose.

Still, the listed air filter didn't fit nice.

 

Junk it. Get one that fits.

Next, use Search on those codes and read the usual causes, then work through the fixes. Easy

 

The airbox is a PIA to close even with an air filter that fits.

 

I like Purolator oil and air filters and have used them for decades on many different vehicles with zero problems. But the Purolator air filter that Purolator's own application guide says will fit our 2005 S-Type did not - it was perhaps a half-inch too long....

What fit perfectly was an STP SA9513 air filter from AutoZone. Less than $20 last October. Installed it then, and the car has run just fine ever since....

This experience taught me to take the current air filter footprint traced onto a large sheet of paper with me into the store to compare to the available products before actually purchasing....

Removal & installation hint: Take the entire airbox out of the engine bay to swap out the filter. You'll be glad you did....

 

yes MOST aftermarket filters DO NOT fit and Im amazed how many I see come in for work from oil change station with wrong filters. They just stick em in and could care less if correct, "Thats the one it calls for, must be fine"

removal & install tip: Dont need to take out the box, just dont unhinge the cover. Unlatch it, pull up enough to slide out the dirty filter and slide in a new one and fit evenly with your hand.
If you unhinge(or someone left yours unhinged) then by all meens remove it then, Yes it will be alot easier to rehinge...

 

I see Jon89 saying the Purolator replacement filter for his 2005 was too long and that the STP SA9513 was a good fit. I would like to add that the Fram CA9513 is also too long by about 3/16". I was able to squeeze it in there, but will try for a better fit next time. Thanks for the info on the STP filter.

 

Be careful "squeezing" filters in that do not fit correctly. It has been noted that it is possible for the lid hold down clips will pop open. Just FYI

 

Thanks Rick, I will keep an eye on that.

 

Hi JPicasso,

Visteon was the original equipment supplier (OEM) of the air filters for the S-Type and X350, and if you purchase a new filter from a Jaguar dealer it will come in a Jaguar box but the filter will probably be marked Visteon.

The last time I checked, Visteon filters were not sold through the chain auto parts stores, but filters by Mann and Mahle are, and they are both top-tier OEMs that have made many of the OE Jaguar filters over the years. I've also had good luck with the Wix filters sold at O'Reilly and other stores, although one X350 owner purchased a Wix air filter that was about 1/4 in. too long. The Wix I purchased for our XJR fit perfectly.

Cheers,

Don
