⚡️ NGK SIFR6A11 NGK Laser Iridium Spark Plugs: Optimal Blend of Performance and Durability. Genuine OE or Equivalent Replacement Spark Plugs. NGK Laser Iridium Spark Plugs Review

I recently purchased these spark plugs for my automotive needs and was hopeful that they would perform well. As a result of my tests, I determined that they were not up to par. While they do have a long lifespan, their performance was lackluster and they did not ignite properly. As a hesitant buyer, I would recommend looking for alternative options.

When you spend over $50 on a spark plug set and open the box to see this. I wouldn't hesitate to install them. They pretty much knocked a piece of cardboard around 4 loose spark plugs and threw it out the door and that's how I got it.

The product came in a factory-sealed box. The engine was much happier with these new spark plugs. Although the recommended change interval is 100,000 miles, what difference does it make when you change it, even at 50,000 miles. Traction was restored, smoothness and acceleration.
