Rx350 used high quality ratchet clap filter wrench, started collapsing filter before finally broke free! Drain plug was also far tighter than I ever do.
I do filters hand tighten as tight as a hand can do nd reasonable wrench on drain. Why the heck does the factory put them so tight?
 
One time I found a picture of the Honda Assembly line where the installed the factory filters, maybe Lexus got on board as well....

Back in the 1990's I discovered the gorillas who installed our Corolla filters and decided it was best for the dealer to do the first oil change. On our Subarus, they were no issue for me with a 'claw" type oil filter wrench. Sounds like the gorillas are still employed.
 
What you need is a S W I V O I L filter wrench. It's an oil filter wrench with a handle that swivels for giving you clearance.

I always thought the band type filter wrenches were the best for removal.

This is becoming commonplace in today's modern automotive assembly procedures. Factories don't like, or want to tolerate leaks of any kind. So they basically over tighten everything that can. I remember having a difficult time with first oil changes on every new car I ever had.

But far more so now than in the past. Also, as far as filters go, many are installed dry. They don't take the time to prelube the gasket, which doesn't help in the least when it comes to removal later. And it's not just the factories.

Places like dealerships, and joints like "Jiffy Lube" are also guilty of over torquing filters and drain plugs. Many to the point of damaging threads. This is especially true with Aluminum oil pans. Or worse plastic, where you can damage the threaded, molded in metal insert, that can require replacing the entire oil pan to fix.

This is the main reason I never have my oil changed anywhere, except in my own driveway by me. I HATE doing it. And the older I get the worse I hate it. But I would rather bite the bullet and suffer through it, than deal with the consequences, or the ineptness of having it done improperly.

Not to mention the fact that unless you actually observe them opening a sealed bottle, and pour it directly into your vehicle, you have no way of knowing what they are actually giving you, or charging you for. Let alone how much. And as simple as it sounds and is, they manage to screw it up on countless vehicles on a daily basis from coast to coast.
 
What I have found, if a filter is not good and hot , it is more difficult to remove. Some times if space allows , a cap type wrench using an extension and ratchet works much better than a strap type wrench.

Do as I say, not as I do.

Somewhere there's a thread having the discussion on how to correctly tighten/torque oil filters with a P-style gasket, but I couldn't find it. Wonder if this may be related, but doubt it. Certainly not the oil drain bolt.
