Does anyone know how the front and rear "TL" emblem is attached? Are they glued on, or are there clips to be removed?

 

What front "TL" emblem?

The rear emblems for, except the center "A", were just glue/tape on the 3G. The rear center "A" on the 3G was glue/tape with two pins.

I'd expect similar on the 4G. Front "A" is likely to be a good bit more complicated and may be susbstantially different than the 3G.

 

The front A on the grille is screwed into the grille with 3 screws from the back. Ask me how I know, I only remove them every other day lol.

The back is probably just two pegs with some double sided tape at the top.

 

The "TL" and "sh-awd" emblems are stuck on with doublesided foam tape. A lil goo gone and some fishing wire is all you need to remove them. The A (acura) emblems are bolted/pegged on.
