Website Reviews
Loading Reviews...
Part Number: E3.58
Brand: E3 Spark Plugs
Notes: Spark Plug
  • Smoother Acceleration & Idle - The faster flame initiated by the E3 spark plug results in a more complete burn of the ingested fuel charge. More pressure is created against the piston more fuel is put to work
  • Energy - Power output improved by 6% on average in the typical operating ranges-results will vary
  • Efficiency - E3's DiamondFIRE ground electrode ignites the air/fuel mixture faster and more completely, creating a faster and larger flame kernel; more fuel is put to work with less waste; creating better fuel economy-results will vary
  • Ecology - E3 provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
  • E3 Spark Plugs are pre-gapped at the factory to meet O.E. requirements
