Review on πŸ”₯ E3 Spark Plugs E3.70: Maximizing Automotive Performance with 1 Spark Plug Pack by Scott Channell

Revainrating 5 out of 5

quality product! for parts

Very similar to these spark plugs, they are a one piece assembly that will not break on these 5.4 liter Triton engines. We replaced the factory spark plugs with these and a set of Bravex coils and now the truck runs much better. I would recommend these spark plugs to anyone who prefers expensive Autolite, Champion or Motorcraft.

Pros
  • Sleek design
Cons
  • Negative present
