Smooth performance and consistent ignition!
I have been using these NGK (4469) LFR5AIX-11 Iridium IX spark plugs (pack of 8) for several months now, and they are still performing excellently. From the moment I installed them, I noticed smooth engine operation, reliable starts, and overall improved performance. Even after months of regular use, they continue to deliver consistent ignition and great efficiency with no issues at all. The build quality is outstanding, as expected from NGK, and they hold up very well over time. I am very satisfied with this purchase and would definitely recommend these spark plugs to anyone looking for long-lasting reliability and excellent performance.

Worth the money
Used these in my titan and they work like they should. Gap was off but that's normal, each vehicle has its own tolerance on gap. Would recommend if needed and don't want to pay autostore price

Are they the real McCoy?
They seem to work okay, wasn’t expecting any performance boost, just wanted long life. I don’t know if that happened because I sold the truck about 10,000kms later. My issue was getting any feedback from the manufacturer if they were counterfeit or not. After reading some reviews and comments on how to determine if they were knock-offs, I was suspicious They were possibly not genuine NGK plugs. I asked NGK 3 times and no response. If NGK doesn’t care, then they don’t get my money next time, especially after spending a ton of money on 16 plugs for my Hemi.
C**!
NOT LASER Iridium
These were listed as Laser iridium, these are NOT laser iridium. These are iridium ix, still a good spark plug, but i had to purchase true laser iridium plugs from a different supplier for my application.
