I have this 2021 4Runner TRD Off-Road with a failing driver-side dash tweeter. It sounds really bad at mid to high volume. I'm thinking if I can just swap the faulty one out with a matching OEM part, or if I should take this chance to upgrade both dash tweeters. If I go aftermarket, is there anything else I need to modify? Is this simple to install?
 
Skip the OEM and go aftermarket, you'll get way better sound for similar cost. But be ready to add inline resistors or adapters, since Toyota's stock wiring doesn't always play nice with higher-end tweeters

Swapping in an OEM tweeter is definitely the easiest route, you're already pulling the dash apart, it's a great time to upgrade both. If you go aftermarket, 3.5" speakers fit in pretty well with minor tweaks, uou'll likely need a simple adapter or pigtail harness since Toyota uses a unique connector
