Best oil I’ve used is K&N 5w-20, 5 quart jug is what you need. Saw a good reduction in oil consumption.
Pros: best oil, reduced oil consumption

buy a nice K&N air filter and replace yourself.
Pros: good quality
I put a K&N cabin filter and it's been going strong, wash it out and dry, goes back in and still smells fresh.
Pros: wash it out and dry
I bought a K&N cabin air filter. I wash it in my bath tub. Dry it. Take some spray oil I made myself with essential scented oils, rubbing alcohol, and glycerine. Spray it on. Let it sit for 5 minutes in the sun. Pop right in. Completely fine.
Pros: washable, reusable filter
just went to autozone and forked out for the K&N, and holy shit it was worth it. Like night and day on the airflow. I can actually feel it on my face now, lol.
Pros: night and day airflow, can feel on face
Vehicle:
Toyota 4runner
Have a 2025 TPP. Just put in a K&N air filter for about $50. Seems to breathe better and maybe adds a couple HP. I like to think it does lol.
Pros: better breathing, more HP
I have one. I clean it when it starts to smell. I just use simple green to clean it. Now, does it let more particles in that I breathe in? Probably, but no worse than breathing in the air outside. The worst cabin filter I used was the Bosch HEPA. Too restrictive and as soon as 12,000 miles hit, it was clogged and I was miserable for a few days in the summer heat
Pros: easy to clean
Cons: lets in more particles
Mileage: 12000 km
I have the K&N air filter in my Badlands. Difference is very minor.
Pros: minor difference
I will never again waste money on a stupid K&N.
Cons: waste money, poor value
K&N filters aren't really worth it as the increased air flow isn't going to result in any significant gains since air/fuel ratio is computer controlled anyway. Not to mention you would really need better exhaust and a tune to take full advantage of increased air flow. Also, if improperly oiled, they can cause MAF sensor issues.
Cons: not worth it, no significant gains, can cause MAF issues
