NGK 5266 IZFR6K-11S Laser Iridium Spark Plug

Got these for a 2006 Honda Civic with 125K on the original (NGK) plugs. I have had excellent experience with NGK plugs for many years in cars and power equiipment, so I always buy this brand if I can, even if it's a bit more expensive. Perfect fit, car ran a bit better (no surprise, given the miles on the old plugs). Have never had a bad experience with NGK plugs.

So easy to replace. I replaced the 4 plugs before leaving for work one morning... took 10 minutes. I replaced these plugs with just over 80k miles each time. The car has 182k miles which runs like it's new and continues 33-35MPG as a commuter car.

I like using the parts the manufacture recommends. (Since they designed the car to begin with.) These brought the car back to life. Well worth the price.

I checked the gap on these and they were on the money.Soon as I fired the car I could feel the difference.The old ones only had 90k so it was time.Had no problem installing but be careful to not overdo the amount of anti-seize you put on or your torque wrench will not click and I almost overtightened.Just put thin coating on threads and that should do it.

I bought these spark plugs as an OEM replacement for my car. The car was having difficulty starting and stuttered when accelerating. After changing the spark plugs, my starting problems were resolved and the car no longer hesitated while accelerating. NGK has solid build quality, A+ - will be purchasing again in the future.

i put them in my 2006 honda civic lx(yes they are compatible) i bought all 4 here a month later my car misfired in the highway when accelerating luckly i kept the old bosch ones i had previously. i pulled over swapped them back and the flashing engine light was gone and my car was back to normal i bought this because i figured it would give it better performance since its the original ones from the manufacturer. pretty disapointed because if i hadnt kept the old ones it could've cost me a tow..and if i hadnt been able to pull over i couldve hurt myself and/or someone else😐

1000% brand new and authentic made my civic run so much smoother, acceleration better and easier starts.

Spark Plugs are fine and good price - much less than dealer or parts store. 4 separate shipments for 4 plugs! Just before Christmas so each was twice combined with other ordered items. But single plugs were put loose in box so they rattled around. Plug comes out of small NGK box. Luckily no damage - I checked gap and OK. I know packers are rushed, but use common sense and secure item.

Tip top

Bought these for my 08' Civic coupe (EX) to replace mine which had roughly 30K KM's on them I definitely felt an improvement in starting the car and throttle response over the old ones. (The maintenance code came on for new plugs and I bypassed it leaving the old ones in at the time about 5-10K KM's ago) and the car started to feel "sluggish" especially with it getting colder here in Canada.

Funziona bene !!

Perfectas honda civic 2006

Honda civic, 2009, 1.8 100k on the clock. After the new plugs went in the cars runs almost like new. Torque and smoothness restored. No need for any anti-seize NGK have been putting a special coating on the threads for many years. If you put anti-seize on them you will over tighten them. Old plugs came out nice and easy, torque wrench set to 25nm new plugs fitted , Happy motoring.
