Review on 🔥 NGK IMR9C-9H Spark Plug: Superior Performance Ignition Component by Fred Vazquez

The plugs themselves are great. They are NGK legitimate and of the best quality. I immediately felt the difference in my 2005 F4i after installing these guys in place of my old worn out spark plugs. I give 2 stars for the delivery. I ordered 4 spark plugs at the same time in one order using the same card. 2 of them came in an envelope. 1 arrived in a different envelope. and 1 arrived in a different envelope. All four could easily fit in one envelope, so I see absolutely no reason for that. They were all shipped the same day. But to make matters worse, one of the envelopes was delivered a week late meaning I received 3 plugs and then had to wait a week for the 4th.
