Description
4228 084 1102 STIHL Spiral Housing – Genuine OEM Part
The STIHL Spiral Housing (4228 084 1102) is a genuine OEM replacement housing designed for use on select STIHL handheld blowers. This spiral housing forms a critical part of the blower’s airflow and exhaust routing system, surrounding the fan and directing air efficiently while also supporting proper integration of the ignition system and muffler components.
A properly functioning spiral housing ensures efficient air movement, controlled exhaust flow, and safe operation. A cracked or damaged housing can reduce blower performance, cause excessive noise, or expose internal components to heat and debris.
Manufactured to STIHL factory specifications, this OEM spiral housing provides correct fitment, structural integrity, and long-term durability under professional and homeowner operating conditions.
