Installation Tips

To Ensure That You Install Your New Spark Plug Wires Correctly, We Would Like To Offer The Following Installation Instructions And Tips:

  1. Make sure the engine has cooled down before attempting to remove any of the spark plug wires.
  2. To assure correct firing order, remove and replace only one spark plug wire at a time, starting with the longest wire first.
  3. Remove any clips and wire separators, and then grasp the spark plug end terminal and boot. Remove
  4. with a steady rotating pull. (Avoid the use of pliers, screwdrivers, or other tools to remove the spark plug boot.) Clean off any excess grease found on the spark plug end or coil tower with a soft cloth and isopropyl alcohol.
  5. Open the small packet of dielectric grease supplied with the set of Prestolite ignition wires, and apply a very small amount to the inside of the spark plug boot to aid both installation and future removal.
  6. Attach new wire to the spark plug. Reattach clips and route the new wire back through the separators again to the distributor cap or ignition coil. This will assure that you have followed the original wire routing which is designed to keep the wires away from all linkages, the exhaust manifold, other hot surfaces, and any sharp edges.
  7. Place distributor end terminal and nipple over the distributor cap or ignition coil and firmly attach new wire.

INSTALLATION TIP: When you attach the wire end onto the spark plug, distributor cap, or coil, listen for and feel for a click. This click indicates that the snap lock terminal has fully engaged. Note: On any vehicles equipped with a separate coil wire, repeat steps 1 though 5.
