Review on 🔌 E3.56 Automotive Spark Plug by E3 Spark Plugs - 1-Pack by Bruce Marable

Bought these for my 2006 Honda Civic EX and will never buy them again. I use about 3000 miles and had to drag them. They made my engine rough at idle and at lower RPMs my engine made an odd noise. They seem to work well at higher RPMs. Replace your Denso spark plugs and the difference will be day and night. If you have a Honda, you should use Denso or NGK spark plugs. I learned it the hard way.
