Review on Denso (3381) K20HR-U11 Traditional Spark Plug: Enhance Engine Performance with a Single Pack by John Boyce

Revainrating 5 out of 5

OEM connectors! Best Spark Plugs

These are the spark plugs used from the factory. OEM for my 2007 Toyota Tacoma 4.0L. They were well packaged and all pre-drilled to about .042. Fits like the original. I could see an improvement when I first started the engine. Started faster and started smoothly.

Pros
  • Absolutely Amazing!
Cons
  • Doubtful purchase for the elderly
