Installing Aftermarket Spark Plug Wires

Installing Spark Plug Wires with a larger core can give you a smoother running engine, better throttle response, and a more complete fuel burn. Plus, they just look good!

Don't get me wrong, this isn't a hard-core power-adder, but after
trading my Zetec's OEM Plug wires for a beefier set of wires from
FocusSport, it really did smooth out my idle.  It also gave me a
mild boost in fuel economy.  None of this was enough to write home
about.  Bang-for-the buck, there are other options that may be more
"powerful" (Drop in replacement filter from K&N Comes to mind), but
overall, this is an easy hack to perform on both Zetec and SPI engines
alike.

Tools Needed:
Hands

Time Required:
10 Minutes.

Procedure:

Pop the hood and prop it open.

un-bundle your new spark-plug-wires.

Starting with the longest plug wire, one by one, remove them
from the top of your engine, leaving them attached on the
coil pack.

Remove the longest spark plug wire from the coil pack

Use Dielectric Grease (if it shipped with your wires) on the insides
of both ends of the spark plug wire you're getting ready to install
(it should be the same length as the one you disconnected give or take
one inch or so.

If you need to re-use the plastic retainer clips, move them from the
old wire to the new wire as you place the new spark plug wire back on
the coil pack.  Do not hook the other end up to the engine yet.

Do the same for the rest of the plug wires, from the longest one to 
the shortest.  Remember to use the dielectric grease on all connections
if you spark plug wires shipped with some.

After the coil pack has all four new wires on it, install the four engine 
side connectors from the shortest plug wire to the longest.  Make sure the
connectors snap onto the spark plug firmly.

Drop the hood and fire the engine up!  You just installed new plug wires!
