Review on NGK 7544 CR7HIX IX Iridium Spark Plug: Perfect Fit for Bombardier DS90 2002 - Single Piece by Jason Hutchinson

Revainrating 5 out of 5

You can actually hear it working differently, but it has great resonance. I chose Iridium because of the distance.

What is the difference in how it gives spark to the engine? You can actually hear it working differently, but it has great resonance. I chose Iridium because I set the distance to full throttle on a scooter. Although copper is the best conductor, it doesn't have the same durability as iridium.

Pros
  • Amazing
Cons
  • Some errors
