I haven't seen much information on AIS Delete or Smog block off plates for the FJ/Tracer so i figured i would share a bit. I install spark plugs, psr block off plates, and modify the airbox. I typically do these simple maintenance bits on every yamaha i have owned. I flashed the ECU (vcyclenut) and also installed a Delkevic 13 inch Exhaust. If you've considered doing the AIS and haven't found much information, i hope this helps. Thanks for Watching!
