Review on Denso W16EXR U Traditional Spark Plug by Vijin Wisniewski

Revainrating 4 out of 5

They worked fine for me but had no gaps in ALL

They plug holes in my engine and spark when powered. I'm deducting a star for reputation alone. They worked great for me but weren't missed AT ALL. I also heard bad things from the mazdaspeedforums community about the Denso crash so I took them off and went to NGK. I suggest everyone else do the same for the Mazdaspeed3, 6 and CX9.

Pros
  • Ignition Parts
Cons
  • Modern
