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

Revainrating 5 out of 5

Local store never stocks them

I always stick to genuine parts in my cars. Toyota requires these copper plugs on the 2010 Tacoma 4.0, so I drive and change them every 30,000 miles. They look ok, but I'll change them anyway. Get these for your 4.0 taco if you can't find them at your local retailer or store.

  • Perfect for a small home
Cons
  • Almost never
