What's the best air filter to use? - Toyota Yaris Forums

Yes, K&N filters are good. I always run one with a stock air box on my cars.

Don't listen to those who would say a K&N filter will somehow affect a MAFS etc.. That is complete BS. I have been running them for over 10 years without a single problem.
In fact a Toyota TRD filter is made exactly like a K&N but, it is much more expensive.

BTW, don't expect a dramatic difference with a K&N. It will just open up the top end slightly but, it's worth it IMO.
