Thin-Walled Oil Filter Housing Wrench?

I had to deal with this once... An outrageously terrible design Toyota did with this... How I finally got it resolved is a standard cheap oil filter socket that's thin-walled like you're looking for, but you have to modify it so the tabs are bent further in and have to be careful to only put breaker bar pressure on it to the extent it doesn't slip. Obviously the thin steel ones are easier to bend the tabs without breaking, unlike the cast ones.

Once you finally get it off you can either buy and adapater or unbolt the whole mount that threads are attached to so you can replace it with a different part that uses standard oil filters that all Prius use.

Toyota learned this design was terrible the hard way and switched back to Gen2 version when the Gen4 Prius came out. The main problem with this system is that shops who have an expensive socket kit that works on every possible oil filter tend to use those tools with an impact driver which puts the filter on so tight its hard to remove, causing the crappy plastic design to fail when untightening it.

 

I would also convert it to spin on. While you could get a kit from Hybridpit for $185 you can also buy the parts from online Toyota dealers for less.

I think you can go to LKQ and snatch that off of 2ZZ Corolla engine and I think I've seen them on eBay for sale for I don't know maybe $80 something like that I would just go that route I had to take this off one time and a poor situation and I just used my I don't know what they are 12 or 16-in channel locks turned it right off without doing anything to the plastic

 

I don't know where I got it, but I've been using a Performance Tool W54120 for a few years on my Gen 3. It's got slots that engage at the places you've circled, and I've never had any problems with it hitting other things when I use it.

I went with Amayama. It might have been my only option up here, but besides that was one heck of a lot cheaper. Here's my invoice, with 2 wiper inserts as well. I deleted them in a spreadsheet calc, assume shipping charge as shown, and converted (roughly) to US dollars, about $75 USD all-in, not extras, taxes, duties, COD or whatever:




^ over $100 USD cheaper than Hybrid Pit Stop, with shipping, all-in...

Note, there are several iterations of the main bracket, mine has a protrusion to a point at the bottom. Not sure of it's purpose, maybe to direct the drip. It works fine.

And to OP: with a spin-on you get a fresh interface for your oil filter wrench. If you want a VERY durable, no-nonsense one, consider Honda's. It's the same size, compatible with Honda (obviously), Toyota and Mazda, in my experience. This I believe is the latest part no:
