nibbi 49mm Foam Air Filter Universal Motorcycle Replacement – Angled Bent Foam, Clamp Included

NIBBI's 49mm foam air filter is a universal replacement that boosts airflow and protects engines for small to mid‑sized motorcycles, go‑karts, mopeds, and pit bikes.

This high‑performance foam intake cleaner from NIBBI is built to fit a wide range of off‑road and street small‑engine machines (50cc–200cc), offering improved filtration, easier throttle response, and a quick clamp installation. The angled bent design and resilient foam media provide a balance of airflow and particle capture for recreational riders, racers, and DIY mechanics seeking an affordable upgrade.

How does this filter affect my bike's airflow and response?

The open‑cell foam structure increases air volume entering the carburetor while still trapping dirt and debris. That improved breathing can sharpen throttle response and make acceleration feel stronger, especially on two‑stroke and small four‑stroke engines.

• Angled bent foam design for smoother intake flow
• Open‑cell foam balances airflow with dirt capture
• Reported boost in throttle response and usable power

What machines will this universal 49mm filter fit?

Designed as a universal replacement, this NIBBI filter is intended for many off‑road and street small engines, including pit bikes, dirt bikes, scooters, go‑karts, and ATVs. Before buying, measure your intake socket to confirm a 49mm fit and check clearance for the angled shape.

• Fits intake necks around 49mm diameter
• Compatible with 50cc–200cc two‑ and four‑stroke engines
• Works with common small engines including GY6 and pit‑bike setups

How easy is installation and routine maintenance?

Installation is straightforward: slide the foam filter over the intake and secure it with the included adjustable clamp. Routine care requires cleaning, oiling (if using foam filter oil), and reinstallation—simple tasks for home mechanics that extend filter life and performance.

• Includes adjustable clamp for quick mounting
• Foam is washable and reusable with proper cleaning
• Measure intake and clearances before fitting to ensure correct placement

Does this filter require special parts or change engine tuning?

No unique parts are required for installation beyond the supplied clamp, but changes in airflow can sometimes alter fuel requirements. For performance tuning or if you notice running changes, check jetting or carburetor adjustments—common practice after increasing intake flow.

• Comes ready to mount with an adjustable clamp
• May need carburetor tuning if airflow increases significantly
• Suitable as a direct replacement for many stock filters with 49mm necks

Who is this for: Riders, racers, and DIY mechanics with small‑to‑medium displacement machines who want a durable, reusable foam filter that improves airflow and offers reliable protection. It’s a practical, cost‑effective upgrade for pit bikes, dirt bikes, go‑karts, mopeds, scooters, and ATV enthusiasts who check fitment and perform basic maintenance like cleaning and oiling the foam media.
