igniiton Coil Replacement For Lexus GS430

 

The GS430 used the 3UZ-FE. This engine replaces the 1UZ-FE used in the previous generation GS, LS and SC. This 4.3L V8 uses 8 independent ignition coils that allow for the ECU to control the engine for better all around performance, fuel economy and emissions. As these coils age, they can fail and cause the engine to misfire. If you have an OBDII scanner, you can see if you have a misfire code (P0300 through P0308 on this vehicle). Switching ignition coils between cylinders and re-scanning the computer will easily tell you if you have a bad ignition coil or another problem. Other common failures of these coils are the plastic shaft itself. If you see any cracks on the shaft, the coil needs to be replaced. If one coil failed, and the other 7 are old or original, it is likely that they may fail soon. Many owners have even experienced coils failing just days apart. W We have the full set of 8 coils for competitive prices. Select the year of your GS430 to find the ignition coils you've been looking for.
