It never was a question for me, but it was for you.

The plugs can definitely go the distance, be it 110k miles or more.

My concern would be if you wanted to replace the plugs when the car is for instance 28 years old, I would be worried about them not coming out of the aluminum head. Aside from that, I don't see a reason to replace them now.

That's a good point and I'm leaning towards doing it when I have the TB done for that very reason.

I already told him that.

If its paid off and takes you from A to B reliably...drive it till you get tired of it or if someone T-bones you

Ouch. A 95 year old man got "confused" and t-boned my wife's 99 RX while it was legally parked. It was a meticulously maintained, mint condition cream puff totalled by State Farm. Body shop estimates car was going 40-45 mph. Wife and her friend were just leaving nearby restaurant and escaped serious injury or death by a few moments.

I second the motion. And if you have, or will be treating the RX to synthetic oil, not even bother to do the TB. Replace it only if it ever goes. Other things are more likely.

Of course i hope no one gets T-boned. Glad your wife and her friend were able to escape serious injury. These RX's are built pretty tough. There was a story in my local paper with someone walking away from an accident with their RX, besides the Toyota dependability, it was one of the factors that i kept in mind when i purchased my 02 RX.
