Denso recommends 60,000 service life for iridium plugs, Lexus recommends 120,000 . kind of like they recommend lifetime transmission fluid that they do not make. discuss

Im not sure which connectors u are asking about.....but I did not break any clips or boots.....but I really took my time with this project. No real noticeable performance improvement.....except in my mind......but I believe the service needed to be done.

This is the very reason that at 119,000 miles with my 01 LS430 running like a champ and accelerating and idling perfectly, I have decided to hold off on the spark plug replacement. I only drive 5,000 miles a year which shouldn't change things very much. .

The 2nd or 3rd plug on the driver side can easily be removed in a minute without the socket attachment that has a universal joint. That socket attachment is required for some of the other plugs, along with the extension.

let it ride if u only drive 5k a year......u saw how mine looked w 135k on them. Im just a perfectionist. If u are handy I agree taking a quick look might satisfy your curiosity....but if your car is running great they will look just like mine did.

Ya no real performance difference after plug change but nice to know it is done. Not sure why they used diff plugs. I am impressed that u are tackling the timing belt.......u are saving a ton of money.

yeah, I've got a ton of 'deferred' maintenence I'm doing right now. It's my wife's car and she's out of town for 3 weeks so I'm getting it all done. Main thing is T-belt but "while I'm in there" I'm also changing the plugs, replacing brake fluid & transmission fluid and I might take this opportunity to swap the air sus out for the OEM steel spring setup. I bought the complete setup on Craigslist a few years ago and have been waiting on the air sus to go out. Might just change it over and sell off the air components.
