Automotive aftermarket air filter for small-displacement bikes, promising cleaner intake and a dependable 42mm fit. Riders gain peace of mind from a corrosion-resistant clamp and resilient rubber connector. Is the RUTU 42mm Air Filter the right replacement for your carburettor and engine?
⚡ At a Glance
- • Filtration Efficiency: Bent foam sponge captures particulates while allowing steady airflow through the 42mm inlet.
- • Best for: Owners of 125cc GY6 mopeds, 140 YX LIFAN horizontal engines, and 125 to 200cc vertical-engined pit bikes
- • Not ideal for: Engines without a 42mm inlet or machines requiring an OEM-specific airbox fitting
Bent foam sponge element mates to a 42mm inlet via a rubber connector and stainless clamping band. Aftermarket replacement aimed at common 125cc and 200cc small-engine applications.
Cleaner airflow, with bent foam sponge element
Open-cell foam traps dust and debris while maintaining airflow through the 42mm inlet, balancing filtration and breathability. Foam construction slows particulate passage without blocking carburettor feed.
Cleaner intake reduces abrasive wear and helps carburettor jets remain clearer between services, supporting steadier running.
Secure fit and corrosion resistance, with rubber connector and stainless clamp
High-grade rubber connector forms a tight seal on 42mm fittings and absorbs vibration, while a stainless clamping band resists rust and retains tension. Stainless resists common corrosion that affects iron clamps.
A tight, rust-resistant connection lessens air leaks and requires less maintenance in damp or dusty conditions.
Broad compatibility, with 42mm inlet sizing for common carburettors
Designed for carburettors and engine layouts that use a 42mm inlet, including compatibility notes for PD24 and PZ30 styles. Fitment covers both vertical and horizontal small-displacement engines listed by the manufacturer.
Direct replacement option for many mopeds and pit bikes, avoiding the need for custom adaptors where a 42mm inlet is present.
