Overview:
This Air Filter Base is a genuine Stihl spare for compact petrol chainsaws, built to secure and seal the air filter for clean intake air and reliable running.

It is a direct-fit replacement for worn, cracked, or warped bases on Stihl MS151 C-E and MS150 C-E models, helping to prevent dust ingress, poor starting, and erratic idling. Supplied to OEM specification under part number 1146 140 1201, it offers an accurate fit using the existing fixings. Genuine Part status ensures compatibility, durability, and long service life in both professional and domestic use.
