Description
35mm Air Filter for 50cc-125cc ATV & Dirt Bike
Keep your small-displacement ATV or dirt bike breathing clean with the iFJF 35mm Cone Air Filter. Designed as a direct-fit performance upgrade for 50cc, 70cc, 90cc, 110cc, and 125cc Chinese engines commonly found in SUNL, TaoTao, Coolster, and other pit bike brands. The 35mm flange fits most stock carburetors on these platforms, replacing the restrictive factory air box with a free-flowing foam element that improves throttle response and top-end power.

Why Upgrade from Stock Air Box?
Factory air boxes on budget Chinese ATVs are notoriously restrictive. By switching to this high-flow foam filter, you gain: better throttle response, longer service life (washable/reusable), lower maintenance cost, and improved intake sound.
Installation Tips
- Remove the stock air box assembly (2-3 bolts and a clamp).
- Slide the 35mm flange over the carburetor intake throat.
- Tighten the included hose clamp until snug — do not overtighten.
- Ensure filter clears exhaust and suspension components.
Frequently Asked Questions
Q: Will this fit my TaoTao 110cc ATV?
A: Yes. Most TaoTao 110cc ATVs use a PZ20 or PZ22 carburetor with a 35mm intake flange.
Q: Do I need to re-jet my carburetor?
A: In most cases, no. Stock jetting on 50cc-125cc Chinese ATVs runs slightly rich from the factory.
Q: How often should I clean the filter?
A: Every 5-10 riding hours in normal conditions, after every dusty ride. Use foam filter cleaner, never gasoline.
Q: Is this filter street legal?
A: This filter is intended for off-road use only. Check local regulations before use on public roads.
