Part# 11-08060
MFR Model# LS03-01004


This is a replacement part for existing alternator filters. This filter's wire won't break at the case and its clamp is made from heavy gauge steel. Double the capacitance compared to OEM alternator filters, which results in a better performance in the elimination of RFI generated by aircraft alternators. For stubborn alternator noise, this Alternator filter combined with the Eliminator (P/N 11-08055)can trap a wide frequency range of electronic noise. Both of these filters have been thoroughly tested under a DO 160D and are FAA/PMA approved.
