1NRFE Spark Plug SC16HR11 Recommendation Pls

[mik23]

Hi

The car has only done 50k 1NRFE Engine
I have taken out spark plug and cleaned them with cleaner due to lack of power sometime.

Can anyone help if they need replacement

No codes
No DTC
No stalling
No shaking
Car runs fine however i noticed on torque software misfire count so i am bit confused

any recommendation would be highly appreciated.

ignition coils work in tandem with your plugs so check them on the particular cylinder with misfire.

How can I test the coils than ?
