Hello guys.
I recently purchased a 2001 Buick Regal LS from one of my friends and I love it. Well, I am planning to replace the plugs and wires because I am planning on having this car for a long time. Can anyone help me choose between platinum and iridium plugs? I read somewhere that iridium plugs are supposed to last longer. Can anyone confirm this? I am looking to maximize the fuel mileage. So what do you guys suggest?


Thanks..

I won't address the question of better fuel economy, but I will say that I haven't replaced the plugs in a car since I started buying new ones in the early 90s. And we used to put something around 40K miles a year on two vehicles (each).
