Protect your engine from catastrophic masonry damage with the genuine OEM STIHL Air Filter Maintenance Kit. Purpose-built to conquer the punishing dust clouds generated during dry concrete slicing, block cutting, and street demolition, this heavy-duty factory kit is tailored specifically for the legendary STIHL TS 400 Cutquik® gas saw. Routinely replacing your entire intake cluster with original equipment parts is the single most effective way to maximize cylinder compression, maintain smooth throttle response, and avoid costly piston scoring.
This premium 4-piece maintenance kit utilizes a high-efficiency multi-stage filtration defense system. It comes complete with the main pleated paper air filter element, the high-density inner auxiliary safety filter, a flock-coated foam pre-filter wrap, and a precision-molded replacement housing gasket. Working in harmony, the foam pre-filter deflects coarse sand and aggregate chips, the main pleated paper element traps micro-fine concrete silica dust, and the inner auxiliary element acts as a final fail-safe barrier, keeping your 2-stroke engine breathing clean, unrestricted air under full 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 high-grade compound gaskets that compress 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 kit exclusively for the STIHL TS 400 Cutquik® cut-off saw. Please verify your saw model and parts manual configuration before purchasing. Kit includes all four essential components in original OEM packaging to ensure a complete intake box overhaul.
