Here is a little more info I obtained from NGK's web site. They say the Iridium IX plugs will give 40-50 K miles and that the Iridium Laser plugs will give 90-100K miles. They say the iridium tips plugs do not have a platinum base and the base wears out first. The Iridium Laser plugs have a iridium tip and platinum base. NGK calls the Laser plugs OE. I thought the OE were copper. The Iridium IX plugs cost more than the Laser plugs. If it wasn't such a PITA to change these plugs, I wouldn't be so concerned about the plug choice. I also need to think about how much longer I am going to keep this truck. Over many years and vehicles I have found that if I special order a vehicle, and get exactly what I want, I am happier and keep the vehicle a lot longer, I've had this truck for 6 years now, since new.
