Hey guys, I am changing out my plugs tomorrow and I am thinking about getting some NGK Iridium IX's. They are on sale at a place near my house for 25 bucks. Anyone use these? Are they worth the money?

^ this. Just save your money on basic coppers. There really isint a performance benefit on our cars. Ive run Iridiums, platinums, and coppers. The others are just good hot spots to cause detonation or pre ignition if you start adding signifigant power to the car...

Stick with the standard NGK plugs..about 2 bucks at any auto parts store...and change them out at about 30-35k miles...save your $$$ and avoid all of that other stuff...no performance increase at all...just a lighter wallet
