Spark Plug Question

After researching on the net it seems most people swear by the NGK plugs, the manual says NGK plugs, the dealer told me NGK plugs.

I check the maintenance forms from the PO and see "Autolite" and gasp. So needless to say I'm going to replace those with the NGK plugs/wireset.

My question is which plugs to get? I was looking at G-Power vs Iridium IX. I was curious opinions on each.

Depends on which year / motor you have.

Don't waste your money on Iridium or any other hyped "will increase hp and gas mileage by 2billion percent guaranteed!" plugs.

Thanks, I'll check out those links and see what I can come up with.

And thanks also, I didn't realize that I didn't have any sort of info on the car. So added it to the sig.

Looks like the NGK BCPR6ES-11 is what you need. Make sure you use anti-seize on the threads ($1 from the parts store).
