Moturo Sport Air Filter 90° 35mm connection type 21 for motorcycle ATV quad

Moturo Sport Air Filter 90° 35mm Connection Type 21

The Moturo Sport air filter with a 35mm carburetor connection and 90° angle for motorcycles, ATVs, and quads — the classic modification to the intake tract for increased air throughput. Metal insert, rubber flange, and adjustable clamp, ready for installation.

The air filter sits directly on the carburetor intake and accelerates the airflow in the intake tract, which has a positive effect on engine performance. The mounting width is 35mm; the rubber flange is flexible and fits snugly onto the carburetor thanks to the adjustable mounting clamp. The metal insert supports the filter body and keeps the filter stable, even under vibration and heat.

Replacement takes about half an hour with a screwdriver for the clamp and a bit of finesse when attaching it to the carburetor.
