A Solid Copper Core And Its Nickel Tipped Electrode Provide a Longer Plus Life.
Offers Better Engine Idle Stability And Smoother Performance.
Allows For Smaller, More Efficient Electrode Designs For Improved Cold Starting And Quicker Acceleration.
Fine-Wire Electrode Helps Improve Ignition Of The Fuel And Burns Away Carbon Deposits On The Tip Of The Plug As They Form, To Help Improve Fuel Economy.
One Piece Suppressor Seal Blocks Radio Frequencies That Can Affect Vehicle Electronics.
Suppressor Seal Meters Spark Energy For Longer Electrode Life And Seals Against Combustion Leakage.
Visually Inspect Spark Plugs For Signs Of Wear. Follow These Steps For Removing Spark Plugs For Inspection, Servicing Or Replacement:
Grasp The Spark Plug Boot And Gently Rotate It 90 Degrees Counterclockwise. Pull The Spark Plug Boot And Cable Away From The Spark Plug. If Necessary, Use a Spark Plug Boot Removing Tool. Do Not Grab Or Violently Pull Spark Plug Cables.
Brush Or Air Blast Dirt Away From The Well Areas Before Removing Spark Plugs. Caution: Use Goggles To Protect Eyes From Debris When Applying Compressed Air To Spark Plug Wells.
Use The Correct Deep Socket Size To Loosen Each Spark Plug One Or Two Turns. Note: To Remove Spark Plugs From Aluminum Heads, Allow The Engine To Cool. The Heat Of The Engine, In Combination With a Spark Plug That Is Still Hot, May Cause The Spark Plug Threads To Strip The Cylinder Head Upon Removal.
Remove Each Spark Plug And Place Each One In a Tray By Cylinder Number. This Will Help Identify And Relate Any Unusual Condition To The Cylinder Involved.
Apply Dielectric Grease Into The Boot Area To Reduce The Chance Of Exterior Tracking On The Buttress Tower Of The Spark Plug. This Grease Also Promotes a Good Heat Transfer Between The Spark Terminal Screw And Boot Terminal.
Before Installing New Spark Plugs, Use a Gap Guide To Make Sure Your New Spark Plugs Have The Correct Gap.
Install Spark Plugs Or Glow Plugs To The Proper Torque Per The Manufacturer.
