Stihl Air Filter Kit for CutQuik Saws - TS410, TS420, TS500i

Protect your engine from catastrophic masonry damage with the genuine OEM STIHL High-Efficiency Air Filter. Purpose-built to conquer the punishing dust clouds generated during dry concrete slicing, block cutting, and street demolition, this heavy-duty factory element is tailored specifically for the industry-standard STIHL TS 410 and TS 420 Cutquik® gas saws. Routinely replacing your intake filter with original equipment parts is the single most effective way to maximize cylinder compression, maintain smooth throttle response, and avoid costly piston scoring.

This original equipment manufacturer filter features a premium pleated paper design that optimizes the filtration surface area without restricting vital engine airflow. The closely packed, industrial-grade pleats capture micro-fine silica dust and abrasive concrete particles before they can breach the intake tract. By facilitating clean, balanced airflow, this filter ensures your high-performance 2-stroke powerhead operates at its ideal fuel-to-air ratio, keeping your engine cooling uniform and power delivery completely stable under load.

True OEM Integrity vs. Cheap Aftermarket Failure: Abrasive concrete dust can score a cylinder wall and ruin a high-performance saw engine in a matter of hours if an intake filter fails to seal properly. Genuine STIHL elements feature exact-tolerance molded dimensions and a specialized flexible sealing perimeter that compresses perfectly into the factory filter box housing. This absolute seal stops "dust tracking"—the dangerous bypass of contaminated air along loose edges that routinely destroys engines running substandard aftermarket filters.

Fitment & Installation Note: Designed as a direct factory replacement component exclusively for the STIHL TS 410 and TS 420 Cutquik™ cut-off saws. Please verify your saw model and parts manual configuration before purchasing. Filter comes individually packaged in original OEM STIHL branding to guarantee absolute authenticity.
