Time to change plugs on my '06 GXP and I was looking into replacing original plugs with OEM Platinum or paying a little more and upgrading to Iridium plugs. Anyone have any special preference or insight that may help??? Most of what I've read as far as difference is only the lifespan between the two. Not having any big issues right now with performance or fuel economy. Obviously, new plugs will offer some improvement, but any noticeable responsiveness or improved economy, etc between the two to justify the extra cost??? Also planning on changing the wires while I'm at it. Waddaya think??? OEM or go with a performance set???
Thanks!!!
