this would be a nice topic to learn from each other, tell us what you did different to improve your Corolla.
I have a 2017, engine is a 1.8 and got rid of the dealership oil and tried something different:

also bought the wix cabin filter.
also installed this TRD exhaust

a bit pricey but I am happy with it.
