When to Replace

• Clean loose debris from around the air-filter housing before opening it.
• Remove the used main filter and foam pre-filter, then check the housing for dirt or damage.
• Install the replacement filters in the same orientation as the removed components, ensuring the cover closes securely.
• Do not install this filter on a 150BT built before 2022.
