I had the original SK20R11 plugs in my 2004 V8 T4R for 98,000 miles and it performed just fine. The owners manual says 60,000 but the parts guy said iridium plugs are good for 100,000. I had a long trip coming up and I didn't want to take any chances so I changed them at 98,000

I went to a Denso Products site (not Denso) and they say the iridium long-life plugs are good for 120,000 miles. The Denso TT (twin tip) are good for 100,000 miles and the iridium power plugs are good for 30,000.

At the Denso site they say the plug models beginning with “S”, “Z”, “F”, “D”, and “V” are Long-Life plugs are are good for 100,00 km, not miles. Mine is the SK20R11 model so it appears I'm good for 60,000 miles. [100,000 km = 62,137 miles]

The owners manual says 60,000 miles or 72 months then 120,000 or 144 months. It's been 60 months but only 34,00 since the 1st change at 98,000 / 14 years. (Yes, 14 years or 168 months. I bought my T4R as my retirement vehicle so I drove it about once a week to work, 48 miles round trip, if there wasn't any snow/ice/salt until I retired in 2013. There was the occasional fishing trip as well.)

I already ordered new plugs and I'm at 132,000 miles right now. I may pull a plug and see what it looks like. Since it will be 60 months next month, I'll probably change them, getting back on track for time instead of mileage.
