Pike 150-160 Air Spring Challenge: Which one?

Since the parts are super hard to come by at a shop, we are looking for the 160 Air Spring to increase the travel on my son's fork (2020 Specialized Expert w/RockShox Pike RC, DebonAir).
Will one of these work?

What is a C1? 050? Getting lost in all the part numbers.

Have you been here yet to find your fork?

That gives more info to work with but it still confuses the hell out of me.

C1 is the most current/updated air spring (the one you want). The 050 air spring at the link is the newest C1, but compatible with the earlier Pike A1 29" 2014-2017 (not what you want).

You want part number 00.4020.552.000 (the 070 one). BTW I believe retail on those is $42, so those C1 options at PB seem a little high.

Thanks! Very helpful. All that stuff confuses the hell out of me.

Also, if you order from a retailer or local shop, they should be able to confirm the correct air shaft.
