Cabin air filter & engine air filter condition after 9 month, 7600 miles (Hybrid ORP)

• Toyota does not publicly publish detailed micron efficiency ratings for most OEM filters, making direct comparison difficult.
• “Higher filtration efficiency” can involve tradeoffs with oil flow restriction.
• A filter that captures smaller particles is not automatically “better” for every engine design.

I've seen this information before. I'll pose these questions just out of curiosity & not out of criticism of others choices of how they care for their vehicles:
• Why wouldn't Toyota want to publicly publish the detailed micron efficiency ratings for their products when nearly all aftermarket manufacturers do so?
• It is possible that higher filtration efficiency can result in potential oil flow restriction...but aftermarket automotive oil filters are manufactured to meet or exceed the OE oil filters performance including oil flow & filtration efficiency. I'm pretty sure that respectable manufacturers are required to perform testing to ensure that their products aren't grenading vehicles as that would be determental to their customers & their company. There is also likely regulatory agencies involved in this as well. An owner can also compare the before & after oil pressure gauge readings on their instrument panel display to decide if they want to continue using oil filters other than OE Toyota.
• What is “better” for an engine design is usually open for debate in filtration matters...but how can having cleaner oil circulating through today's modern turbocharged engines be a bad thing as long as the oil pressure & resulting lubrication is within tolerance?

Lol another oil filter thread!

Toyota engines run clean in general and don't necessarily need 99% @ 20 micron efficiency in their filters.

Because Toyota buys 999999999 filters from Denso each year, they do spec cheaper filter media that causes their filters to be known as rock catchers.

Denso filters are good, but built to a price point.

Nothing will happen if you use OE Denso vs aftermarket Wix / Mobil 1 / etc.

Not my intention to derail or make the thread into “another oil filter thread”. It doesn't have to be. The OP started it about air filters but oil filters are a related topic. Nothing wrong with exchanging ideas, opinions & posing questions. No one knows everything...I certainly don't. Owners can do whatever they want to do with their own vehicles based on their own level of knowledge & risk acceptance. All said of course with open mindedness & respect.

I've not looked at mine yet but I'm all about being proactive rather than reactive with the maintenance & changing things. I need this 4Runner to last me for 15-20 years if I can help it.
I live in a large Texas city where there is always dust, dirt & construction going on. I also freeway drive 45 miles to work 3-4 days a week. So I imagine it wouldn't hurt to change my filters early & often.

Quality third party, after market filters vs. Toyota OEM filters aren't going to make any difference at all. My take is best to use Toyota parts because they are designed specifically for their vehicles.

Toyota oil filters are acceptable quality but still mediocre compared to some other aftermarket brands. They are on average only about $7 though so they are afforable mediocre quality if anything.

Can you point to evidence or data that supports your claims about Toyota oil filters?
