Hey all,
this may seem like a pretty dumb question but as usual, I go to buy parts for my car and there are multiple part numbers that come up with no real explanation of what the differences are... here is my dilemma... i want to replace the plugs and wires on my car as I have personally put 60k on the car myself, 105k total on the car. I have zero clue if the wires have ever been changed but I'm willing to bet the plugs have been at least once. After reading a TON of stuff on both this board and clubgp.com, I have decided to go with AC Delco iridiums (41-101) and AC Delco plug wires BUT there are 2 part #s that come up for what fits my car and no idea what the difference is other than about 20 bucks. I am looking at rockauto.com to buy and they list AC Delco part 746BB ($43.79) and 9746BB ($26.79). Their ground shipping is only about $6 but basically looked everywhere and cannot find what the diff is between these nor what my car's original OEM part number is for the plug wires. The other thing is that advance autoparts sells the 746BB part for $71 but says at the top on their website that it's superceded by 9746BB.. sooo.... does that mean 746BB has been replaced by 9746BB?? If so, why would anyone still sell 746BB?? I seriously have never been more confused buying parts for any of my cars than I have been with this car. It seems like there are 2 part numbers for every part I need and I have to do weeks of research just to find out which part is the correct one! BTW, my car is a 2000 GP GT 3.8 NA. Any help is much appreciated.
