Review on 🚀 Maximize Performance with K&N Cold Air Intake Kit: Boost Horsepower for 2006-2017 TOYOTA (Yaris) 69-8612TFK by Brandon Addison

As they say, you get what you pay for. Yes, it's expensive, but this piece is well made, comes with simple instructions, and is well thought out. A big plus if you are using this on a Yaris and planning to replace the throttle body with a Corolla 1ZZFE throttle body. The diameter of this air intake matches the 1ZZ throttle body, it is actually slightly larger than the stock 1NZFE throttle body. On the test bench I could not find any real increase in performance. Although the car sounds good once you put your foot in it.
