S-AFC

Super AFC. Is and after-market air flow converter made by A'PEXi. The Air Flow Converters work by intercepting the signal between the car's air flow meter and the ECU.

The Air Flow Meter is the device that tells the ECU how much air is entering the engine so that the ECU can add the correct amount of fuel.

Dude I just installed a S-AFC on my car and boy is it chipping black bow.

S.F.P. 

Sleeps Fo' Pretenders. A sentiment originally expressed by gangstas and other ruffians, but now simply reiterated by college and overworked high school kids. Sometimes used to ridicule their lazy counterparts.

Kyle: I was all night finishing up an essay for Spanish and studying for my Subject SATs.
Mark: Haha, that's rough, I just played video games and then got, like, eight hours of sleep.
Kyle: S.F.P., motherfucker.
