- Will this fit my Toyota?
- Only if your engine specifies the 9775 plug number. Check your owner's manual or the plug currently fitted. Toyota uses several plug types across engines, so the number matters more than the brand.
- How is this different from a standard copper plug?
- The iridium center and platinum ground electrodes wear far more slowly, so the plug holds its gap longer. That means fewer changes over the life of the car.
- Do I need to gap these plugs?
- They usually come pre-gapped for the listed application, but check the gap against your car's spec before installing. A dropped or bent plug should be re-gapped or replaced.
- How many plugs come in the pack?
- Four. That covers a four-cylinder engine; a V6 needs six and a V8 needs eight, so order the right count.
- Should I replace coils or wires at the same time?
- Not unless they are faulty. Replace the plugs at the interval, and address coils or wires only if you have a misfire code or visible damage.
- Is this better than NGK or Denso iridium plugs?
- They are comparable in design and life. Fit and the correct plug number matter more than the brand, so use whichever matches your engine spec.
