NGK Spark Plug IZFR6K11- Set of 4

I needed a good price on these and was tempted to go to the retail store (Autozoone) but the price was nearly double. I decided to give these a try. What I received is genuine NGK plugs and honestly, I'm sure my Honda ran better immediately after starting up with these new plugs. My old plugs came with the car I bought used. They were Autolite and looked well worn with probably 100K miles or so on them. I posted this positive review because I questioned myself if these "NGK's" are possibly knock offs because the price was quite good. There are a lot of Honda parts being counterfeit these days and platinum based spark plugs are no exception. The other positive reviewers gave me enough confidence to try these.. Notable indicators to me are the over all quality, fit and finish (quality of threads, roll marking, and physical appearance of the Iridium tip on the plug). Also, genuine NGK plugs have in their process a white powder residue on the ceramic portion where it meets the base of the plug and these have this also. At the end of the day, these plugs run fine in my Honda and I'll update the review if I have anything other than my 5 star review. I appreciate getting a good deal on these plugs.

Installed them two weeks ago along with new denso ignition coils and the car is running smoothly(as always). The old spark plugs were ngk as well and lasted over 100k. I installed them on a 2005 accord exl sedan with 218k miles

Would buy again. Good price for some of the best spark plugs you can get. Box came a little squished but product was fine.

Product was perfect condition new and restored my engine performance back to like new.

These were identical to the OEM spark plugs in my 2006 Honda Element. Installed them myself and have had no problems after several months of use.

This item is heavily counterfeited and is expensive and hard to find. Not with these sellers, these are genuine NGK Laser Iridium. I tested them on the Voltmeter and the resistance was in tolerance. These are not counterfeit. Good company.

08' Honda CR-V with 136k miles from on the original Long Life Iridium's with no misfires. I was going to go the Ruthenium route as I have those in my Tundra and really like the performance, but when it boils down to the tried and true of NGK's Iridium Long Life, I figured why go $20 more for something I don't necessarily need, and place it in something that I really trust. not that the rutheniums are bad, I can tell a difference, especially on start up, but I have no long term experience yet.Keep in mind though that in 2022 NGK expanded production so instead of saying "made in Japan" the plug was stamped "assembled in USA with Japanese parts" don't ask me how they fit that on the spark plug, they just did. But comparing the 16 year old plug to this one, it was apples to apples. I've no doubt these will last beyond my tenure with the car.

Great spark plugs for Japanese cars.
