203.0155 OEM Polini Racing Air Filter for Yamaha Zuma 4 Stroke Zuma 50F 50FX and C3. Polini High Performance Dual layer air filter for the Yamaha C3 Zuma 50F and 50FX scooters. 2017 Yamaha Zuma 50FX YW50FX.
The best 1st upgrade for you scooter, This Polini air filter is 100% better than stock! Just look at the breathable screen and the spongy filter compared to original K&N type filter. My Yamaha C3 blows through like the wind!
I used it on a 2007 Yamaha C3 scooter. It fits perfectly and install is the same as a factory air filter. My scooter now has a louder induction sound under acceleration, I really like it.
I did other mods at the same time so I cannot confirm a increase in power.
