Forced Performance -4AN Inline Oil Filter

The FP -4 AN Filter features a 10 micron replaceable filter element that captures oil contaminants in its basket. The filter basket is easily removable for quick inspection and cleaning. The filter can be run in either direction, but the preffered flow direction is in the female side and out the male side. This allows all the contaminants to be collected inside the filter basket rather than collecting the contaminants all over the outside of the filter basket.

The filter is made with female 4AN at the inlet side and male 4AN at the outlet side. This allows the filter to install into virtually any 4AN line without additional fittings.

These filters are designed to fit inline with your turbo oil supply line. The filters are color coded for their orifice diameter:

• Red filter is .125" for full flow with FP journal bearing turbos and Xona Rotor turbochargers (post 2020)
• Purple filter is .020" for use with our Xona Rotor turbochargers (pre 2020) 
• Black filter has a .030" restrictor and is used in Garrett based ball bearing applications.
