They are still available. I used them both and AP1 is a little more streetable, so if it’s a DD and you spend a lot of time in traffic and using the A/C, that’s a better option. On the other hand, if most of your driving is in the upper RPM like fast mountain driving or track days, the ACT is great for that. It can certainly be driven on the street, but it’s not so fun when you’re running the AC because of the extra drag from the compressor slowing down the engine between shifts. That’s my amateur opinion on those 2.
