Turn off that annoying check engine light after installing an off-road X or H pipe on your 1996-2004 Mustang.
Keep the MIL light from coming on with a set of MIL eliminators for your 96-04 Mustang or 99-04 Lightning. When installing an off-road H-pipe or X-pipe on 1996-04 V8 Mustangs, or off road mid pipes on 99-04 Lightning trucks the Malfunction Indicator Light or MIL will come on. This indicates that the computer is receiving a code from having no catalytic converters. To give the computer the ideal reading you must install an O2 sensor eliminator.
