Review on 🔥 Enhance Performance with NGK Iridium IX Spark Plug LFR7AIX # 2309 PK4 by Lawrence Feldman

Bought for low cost and fast shipping, couldn't find exact same spark plug locally for some reason. Read all the reviews about it being fake for reasons X or Y but they didn't even bother to call NGK and ask. So I called NGK and gave the part number and the 4 digit code on the connector. They confirmed they are REAL and assembled in Thailand in June 2022 with genuine NGK parts from Japan. They confirmed that only candles assembled in the US come with a plastic thread/tip protector, while candles assembled in Japan or Thailand have a cardboard protector. When in doubt call NGK and they will confirm or deny the authenticity in less than 5 minutes.
