1961 Jaguar 3.8 Spark Plug

Part Number: 15602-05051267

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: 15602-05174459

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: 15602-05174506

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: 15602-05174365

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.
