Just got a 350 with 87,000 miles.
I did check the Lexus owners site and I see a service was performed around 60k miles but no explanation.

I am getting ready to do the recall and I don't know if I should ask the dealer to replace the plugs.

Any ideas?

My OE spark plugs had a white or orange triangle on the tip (not the ground strap side, other side). The plugs I replaced them with didn't have the arrows.

This should reinforce what the above user stated.

Marking on top of the plugs means they are factory and have never been replaced

If you got the car used, I would change it anyway. Probably best to perform a full tuneup right after you buy the car especially if you buy it off of someone. I got my car with 70k from someone but did a full tuneup immediately after i got it. Oil, spark plugs, filter, dif oil, etc. for about 150 or so you can buy all the parts and have your local shop do it all for another 100 or so
