The 35F foam filter replaces the plastic/foam 064 intake filter. The 35F filter will not blow off or crack. The thicker foam will help muffle the sound a bit. The filter tucks into the groove in the intake cap.
This filter is very easy to clean with a little bit of dish soap and warm water. It is recommended that you clean it at the end of the day and let it dry overnight.
