Description
The stock paper air filters on the GT250 are restrictive and degrade over time. Combined with the OEM jets, the factory setup is often choked for both air and fuel. This “Stage 1” kit addresses that maintenance reality by vastly improving airflow and correcting the air-fuel mixture right out of the box. The result is smoother power delivery, better cold starting, and instant throttle response.
💎 Performance with the Premium Look!
We use EU-sourced DNA or BMC filters for their superior build quality, washable design, and excellent filtration. The included stainless hardware adds durability and a premium finish to your engine bay rebuild. (This is because K&N is discontinued now!)
