TL 3.2 VS 3.5 engine?
I couldn't find anything specific. I'm curious how Honda/Acura changed the 3.2 & 3.5 engine for the Acura TL. I have the 3G type S. Is it bore, stroke, displacement?

It's bore, they made the engine internal capacity larger and therefore increased displacement. The 3.7l is a bored 3.5l.

its a repost but this is press release the differences between 07-08 TL and TL-S. On the other note my TL-S has mic locate in the rear and front roof by HFL bezel, however that is not the case for my base TL.
