Review on NGK 6578 BPR4ES SOLID Spark Plug - Trusted Standard Model, 1 Pack by Richard Edwar

for my 2021 Zero Turn mower, Kawasaki 23hp engine, spark plug gaps checked to Kawasaki specs, 0.30, set to torque specs and mower started after completing other scheduled maintenance and procedures. Bought 2 more parts for next scheduled service. I always try to use OEM electrical parts in any scheduled maintenance on all my vehicles and equipment, I never buy aftermarket electronics and avoid problems and if so, does the OEM cover the products under warranty against manufacturer defects, just my thoughts , for each of their own.
