Review on Highking 64Pcs Oil Pan Thread Repair Kit: Sump Gearbox Drain Plug Tool Set for M13 M15 M17 M20 - Comprehensive Solution by Christopher Gotcher

I found that my situation is different how I need to use it. I had a blind stop in the oil pan so I had to sharpen the carving tool so it had a flat top, they were rounded. I was able to get it working in my case. If you have a straight through hole, they should fit. but i also had to use some "steel epoxy" in the threads to tighten it up, i would say this set should also come with threaded inserts for different sizes.
