Twin Air Powerflow Air Filter Kit for KTM 250 350 450 2016-2018 154218C

Stock air filters restrict airflow and allow contaminants to degrade engine performance over time. The Twin Air Powerflow Air Filter Kit replaces that factory limitation with a precision-engineered dual-stage filtration system that increases volumetric efficiency while extending engine life. Built for KTM 250, 350, and 450 models (2016–2018), this is a bolt-on upgrade that delivers measurable gains in throttle response and reliability.

The dual-stage foam construction—coarse outer layer paired with a fine inner layer—captures dirt and dust more effectively than stock paper elements, reducing wear on cylinder walls and piston rings. The billet aluminum cage provides a rigid, secure fit with superior sealing compared to plastic OEM designs, while the grease-free sealing ring locks into your airbox for an airtight seal that minimizes bypass. A backfire-resistant foam layer adds an extra margin of safety during aggressive riding or tuning adjustments. Best of all, the washable, reusable design supports up to 40–50 cleaning cycles, making this a cost-effective and environmentally conscious choice for long-term ownership.
