1966 Jaguar Mark X Spark Plug

Part Number: 15634-05051267

Notes: G-Power Spark Plug -- Gap 0.025"

Features:

• Trivalent metal plating eliminates the need for anti-seize. For better performance consider upgrading to a NGK Iridium IX plug. For even greater performance consider upgrading to a NGK RUTHENIUM HX(TM) plug.

Part Number: 15634-05174459

Notes: Iridium IX Spark Plug -- Gap 0.025"

Features:

• The Iridium fine wire center electrode's durability is six times harder than platinum. Iridium alloys extremely high melting point is perfect for today's engines. For even greater performance consider upgrading to a NGK RUTHENIUM HX(TM) plug.

Part Number: 15634-05174506

Notes: Standard Spark Plug -- Gap 0.025"; OE Equivalent Design

Features:

• The solid Copper Core offers superior heat dissipation, conductivity and broad heat range. For even greater performance consider upgrading to a NGK Iridium IX Spark Plug.

Part Number: 15634-05174365

Notes: V-Power Spark Plug -- Gap 0.025"

Features:

• NGK V-Power spark plugs are tested to the highest OE standards. Trivalent metal plating eliminates the need for anti-seize. For even greater performance consider upgrading to a NGK Iridium IX Spark Plug.

Part Number: 15634-05343291

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
