Probably, just saying if you were concerned.
The Mann filter may not be the best for your app. Try a Wix or dealer part. Shop on Amazon or RockAuto if you like. I prefer to buy air filters in person so I can return them right away if there is quality or sealing problems(filter doesn't seal well inside of housing or just not my taste etc).
Correct.
Here is another thought for consideration. Sometimes you will get an increase in silicon from just removing the air filter/re-installing after inspection or at air filter replacement, some dirt trapped in a groove gets loose and is ingested soon later. So, anytime you break a sealed system that is an opportunity for a blip in silicon really.
Have you checked for or recall seeing any dirt/fine dust in the air filtration box or downstream of the air filter?
Sometimes silicon is harmless additive. It doesn't appear that Royal Purple utilizes this, but various VOA indicate it's possible to get trace amounts here and there, so if you give the tolerance of 'noise' being roughly 3-5 ppm, actual dirt ingestion is probably not quite 3 ppm every 1,000 miles for this car. Above average filtration, actually, and probably as good as OE was/is capable of doing.
Make sure whatever filters you get aren't made in China on the box or appearing to be outsourced for a cheap version. Some countries make nice parts, no problem.
If it's hard to find a good one aftermarket, I go OE/dealer part or buy something like a Denso air filter. Amazon and/or RockAuto seell them online, usually free shipping over $25 on 'super saver' orders from Amazon, whatever floats your boat. The Wix filter is a good option. I'm going with that if numbers stress me any more.
All that said, going back to the real point, leave the filter alone between oil changes next time, try to keep oil bottles dust-free and clean. So, if you have to top-off the oil, you make sure potential dirt ingestion is minimal. I always inspect the oil filler cap area on the engine and wipe it down when I remove/reinsert the cap simply because of OCD, brushing away from the opening meticulously not to allow particles to enter, lol.
From observing many UOA,' bad' air filtration starts at rates of ingestion higher than 4-5 ppm / 1,000 miles and IS more of an issue the longer the oil change. Dirt or dust is probably large enough to be caught unless it's like fiber glass particulate size or smaller than 10 micron, might take a few passes unfortunately. The Wix 51356 is 50% efficient at 5 micron and 95% at 20 micron according to the beta ratios, so better than OE oil filters anyway. I think your oil filter selection is fine. For mid-tier, I go Bosch Premium/Purolator PureONE to Wix/Napa Gold/Carquest Blue.
