I’ve never heard of a spark plug break in, and as long as you went same size on the injectors it will be totally fine, the PCM will very quickly learn the difference between old and new

Technically, fuel injectors are controlled by the ecm and the ecm varies injector pulses from sensors. The upstream O2 sensor on the exhaust manifold measures oxygen in the exhaust and feedback signals to the ecm controls injector timing for optimum fuel/air ratios. As soon as the engine's started, the ecm automatically adjusts injector pulses immediately as if nothing was done. Sensors are feeding signals continually for the ecm to adjust spark and injector timing. Injector pulses vary all the time. Spark plugs do not break in. Presuming new ones weren't dropped during assembly, shipping, stocking shelves, and removed from their cardboard boxes, spark plugs are preadjusted with the correct gap for immediate installation. Undamaged plugs go in with startup imperceptible from previous plugs (unless the old ones were severely worn or damaged).

It can be said that spark plugs and injectors are truly plug n' play items. Replacing them can result in improved instant startups with smoother idling.

REWARD EXCELLENCE!
