NGKSpark 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.

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.

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.

Worked perfectly for my 2007 Honda CRV. At 99,000 miles. Replaced coils at the same time. Vehicle seems to be running smoother now with new plugs and new coils.

Great spark plugs for Japanese cars.
