Air Filter Adapter 55-44

The NIBBI 55mm to 44mm carburetor air filter adapter is designed to connect a 55mm carburetor inlet to a 44mm air filter neck with a secure, airtight seal. Built for PWK-series carburetors and other compatible setups, it ensures stable airflow, reduced turbulence, and reliable protection against dust and debris. This adapter is ideal for riders upgrading or tuning their intake system while maintaining durability and ease of installation. Features Precise Size Conversion: Converts a 55mm carburetor inlet OD to a 44mm air filter ID for a tight, accurate fit. Reliable Airtight Seal: Tapered inner bore and reinforced outer wall help minimize airflow turbulence and prevent vacuum or dust-ingress leaks. Durable Material Construction: Made from an oil- and fuel-resistant elastomer (silicone-rubber blend) that withstands heat, vibration, and harsh riding conditions. Easy Installation: Slide-on design allows quick installation with clamps—no trimming required in most setups. Reusable & Long-Lasting: Flexible material resists cracking and deformation, making it suitable for repeated removal during tuning or maintenance. Fitment Fit for PWK Series: PWK30 / PWK32 / PWK34 Also suitable for other carburetors with a 55mm inlet, when paired with 44mm clamp-style air filters. Package Includes 1 set Air Filter Adapter
