What is a good milage schedule to replace the spark plug wires?

When its needed; either by failure or cuts/frays in wire or insulation.

Mine lasted over 150,000 miles before they started cutting out.

Hey fellow Canadian with an 01 Trans Am!

Plug wires aren't that expensive, they are very easy to change. And if they are worn out you are shorting yourself (literally and figuratively) on performance and economy. They wear with age, not just mileage.

Change them.

Until they get cut or damaged dont even bother replacing them.

11 1/2 years on my factory wires, the last 7 years with my 427ci. Close to 180,000 total miles.

They're perfect.

I put Taylor 10.4mm Thunderbolts on my 427ci, they suck *** and 5 of them broke at my first plug change with them after about 20,000 miles. I kept my factory wires and put them back on.

I;'m actually gonna change them out in a week or two just for the hell of it.

Did this guy work at Pontiac? If so, do not listen to him.
