Review on Laser Iridium Spark Plug NGK 5266. Part# IZFR6K-11S by Carlos Jass

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 see a return to work, which is really important. Don't forget the extreme pressure properties, I mean you want them. back right?
