Part Number: 2845-05343295

Notes: Spark Plug

Features:

• 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
