Part Number: E3.52
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 "diamond shaped" side wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and longer flame kernel, more fuel is put to work with less waste; creating
  • 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
  • E3 Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented ground electrode configuration increases the amount of combustion pressure created during each power stroke of the engine, which results in a mar
