Welcome to the forum. The best thing you can do is cross-check part numbers on your own instead of taking other's word on it. I will help you out since you are new.

I just bought 05 front and rear bumper covers from an Acura dealer. If a listing says discontinued, check another one, they're not all updated the same.
Personally I like 05-06 look better.
If you want 04 look, watch some videos of guys who've swapped out different years so you can see all the parts you have to swap. If you don't get them all, likely they won't fit.

 

People have been swapping front ends on these cars since the facelift model came out in 05, but you can't mix and match. The 02-04 has the dips in the bumper cover for the differently-shaped headlights. If you swap to an 02-04 bumper cover on an 05-06, it's going to look weird.

Curious why you're asking? Like, is someone offering you an 02-04 bumper cover for cheap?

 

Is is possible to put an 05-06 front bumper on a 02 RSX...

Like the title says, is is possible to put an 05-06 front bumper on a 02 RSX type S?
