Spark Plug wire upgrade

[frit0150]

I own 1995 Grand Am SE V6 3.1L with 165,000. I currently have basic 7mm plug wires with basic champion spark plugs. The wires are about 2 years old and the plugs 1 year. I would like to upgrade to 8.5 mm MSD plug wires. Do I need to buy better spark plugs as well or are will the ones that I have be good enough? Also, since my car as high mileage, will upgrading the wires or plugs be hard on the engine?

Don't need to upgrade plugs with the wires, but AC Delco Iridium plugs are AWESOME.

You dont have to but Vipey is right those iridiums are awesome and known for their noticible performance.

they sorta go hand in hand in some cases... new AC Delco iridium plugs will take the MSD wires easy...

IMO if you change one you might as well up grade both
and get the most bang for your time and money.

Just my



ps- Iridiums are made from the hardest metal on earth and they do Rock !

Does anyone know where I can find these ACDelce Iridium plugs?

Any parts store should carry them, they are not cheap though. About $6 each, but IMO worth every penny
