Even Toyota is vulnerable...

It looks like there weren't any air filter opinions. My recommendation is the factory paper air filter, replaced annually or at least every 10k miles. The factory filter is not expensive, and a clean paper filter usually outflows a clean oil-impregnated filter. You also have the issue of mass airflow sensor fouling with oil-impregnated filters as well as required annual cleaning. K&N air filters are not a performance upgrade.

For your climate, I would use 15W50 Mobil 1 or similar viscosity if you will never be in cold weather. It has enough zinc and phosphorus if that is your concern. Too much of these does not give you any extra benefit and just risk your catalytic converter. Change more often for IMS cars as well as S models and above to prevent bore scoring.
