I run with an eventuri intake on my 21. No issues with the strut bars.. wallet is empty though.
Do the Cusco strut bars sit higher? Achieve a better look (in my opinion) and better fitment for less than Eventuri...
1. As Tsar said, some are unlockable, but you need to check your build date on your door. 07/20 and after seem to be currently locked.
2. I've been running '20 parts on my '21. I would imagine they are extremely close, if not the same considering I haven't seen any components specifically...
