Laser Iridium Spark Plug NGK 5266. Part# IZFR6K-11S Review

Bought these for my daughter's 06 Civic and they work great, their originals have done over 110,000 miles. I would suggest buying an anti-seize compound to apply to the threads. You can find it here on Revain.

So easy to replace. I replaced 4 spark plugs before driving to work one morning. Took 10 minutes. I changed these spark plugs every time I drove just over 80,000 miles. Car has 182,000 miles, runs like new and fuel economy is 33-35mpg as a commuter car.

These are the same spark plugs that Honda recommends in the owner's manual. I changed the spark plugs in my '08 Civic LX at about 108,000 miles. It's been 8 months and 5000 km, works well. The dealer asked $310 to replace them; Instead I paid $40 for 4. We recommend. Save money and replace the spark plugs yourself!

Bought for a 2006 Honda Civic with original (NGK) 125k spark plugs. I've had great experiences with NGK spark plugs in cars and electronics for many years, so I always buy this brand when I can, even if it's a bit more expensive. Perfect fit, car ran a little better (not surprising given the miles on old plugs). I have never had a bad experience with NGK spark plugs.

The old spark plugs I had in last year seem to make my car accelerate faster and they seem to give my car more power. But I read that they are much better because Honda uses them. I'm not sure though. Now when I start the car for the first time it seems to me that it doesn't start as quickly and smoothly as before. And it feels like he's pulling a little harder to go faster.

I bought these spark plugs for my 08' Honda Civic Ex Coupe after 95,000 miles and immediately noticed a difference in acceleration. Honda charged $250 for the job, which cost me about $43 and took about 15 minutes. Changing the spark plugs wasn't difficult, I didn't use a torque wrench, just a regular wrench with an extension and a 5/8 plug head. The only difficulty I had was removing 2 of the 4 old spark plugs but they eventually gave up and got smaller. Also, I didn't have to split these new…

I mean spark plugs, what can I say. These fit well, good spirit. I knew they would fit when I bought them. They arrived well packaged. Of course, they come in little boxes with cardboard sleeves around one end, just like any other candle you'll ever buy. Honestly I like them because if I put them in my Civic and regularly change the oil to a good synthetic oil I get a lot of gas mileage. . I really don't believe the 'permanent spark plugs' rumors, so I change them every 50,000 miles and usually
