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.

Good product

Installed these plugs in a 2004 Honda CR-V as general maintenance. The plug gap was checked on each one and it was found that none had to be adjusted. The car runs fantastic but do not yet know the mileage improvement. I shopped around and found these OEM spark plugs priced better than anywhere else. Look no further.

I always stay true to NGK when it comes to the JDMs and these are no different! Have held up great for a year and keep my car running smooth. 05 accord 2.4L

Installed and worked great! No issues.

Doesn’t fit 2018 civic hatch 1.5T. Upsetting that it showed as an oem replacement. Took everything apart to then find out it didn’t fit.

They work as you'd expect
