I have a 1999 Toyota Tacoma P/U truck with 128,000 miles on it.
Today it started running "Rough" so stopped by my mechanic to
have it checked out.
Turns out that a spark plug wire had shorted out.
An after market set of four (4) wires were $48 while wires from Toyota
Looks like a straight forward decision, after market parts are the
way to go, but there is one more piece of information that is needed
The original wires lasted 90,000 miles with no problems when they
were changed out with an after market set of wires which only lasted
38,000 before failure.
Based on that information, the Toyota set of wires for $83 looks like
the best deal, and they were installed.
Time will tell if I made the correct decision.
