FI stand for fuel injection (misspelled FJ, my bad)
Should dump FI cleaner in your gas tank from time to time, at least once a season.
Properly used will keep your valves clean from carbon build up, mostly intake.
I do this treatment to all of my vehicles, and the best is if you apply it 2 tanks before oil change. Good luck.
