OEM, by far.
If you compare OEM Toyota filters, they are much better quality than most aftermarket ones. An OEM filter costs -$30-35. And aftermarket one is anywhere between $15-20. Is saving $20 once every 30,000 miles worth risking the engine's longevity?
The expensive parts of OEM parts is labor at the dealer. Just buy the filter from your dealer and change it yourself.
Denso is part of Toyota Group Companies. Denso is to Toyota like Mopar is to Chrysler. So Denso is OEM filter, just in a different box.Can the OEM filters be purchased online? I keep reading that Denso makes a great filter actually. Any thoughts?

Using K&N filter is a perfect way to spend $4000 on engine re-build for the sake of saving $30 on air filter. K&N has the worst dirt retention performance among car air filter.Look at K&N permanent (cleanable) air filter on line (eBay).
The fact that is for a Duramax is really irrelivant. Basic concept of an Air Filter is to clean Air before it enters the engine. Type of vehicle does not charge that.Thank you. The test you cited was for several air filters designed for the GM Duramax Diesel (not for RAV4 filters, OEM or otherwise). In the graphic you posted, the difference from "best" to "worst" is 3%. It's like arguing about how many angels can dance on the head of a pin: 99.93 or 96.80 angels... The best filtration (and greatest restriction to airflow) possible would be provided by a solid steel plate, no? It would be interesting to see your list of people whose engines were ruined by the various types of air filters, including K&N. PS: the OEM Rav4 air filter and the K&N cost about the same, but the "life cycle cost" and environmental cost are vastly different.
When considering filter efficiency, you don't consider the percentage that is retained, but the amount that the filter lets go through. So the real difference in filtering efficiency is not 3%, but 100-99.93=0.07 vs 100-96.80=3.20, almost 50 times difference.Thank you.
