I have a A4 B5 that comes with factory projectors. I think its time for me to upgrade those. I'm thinking about an Acura TL, RL, or Honda S2000 projector. Which would fit and how would I do it?

 

no, no, and no.

 

Why even think of putting Honda parts on an Audi?

 

If you really feel it needs the upgrade get some e-codes.

 

You're talking just about taking the actual lens from the aforementioned headlights and retrofitting them into your own housings? I hope so and I also hope someone chimes in with some good info because I'm interested in that, too.

 

I'm trying to replace the lens. I was old that the S2000 projector lens is the best out there. I'm just trying to get a better cut off line whats in my car right now.

 

Then don't cause yourself the unnecessary work. You have projectors designed to work with the lenses on the headlights. Projectors from other cars are designed to work with the lenses on their housings. Those lenses likely have different angles, and there's a chance that it would skew the beam coming through. Just get HIDs and you'll be happy.

 

This is wrong bro... if you don't know, HIDs shine differently than a normal halogen bulb. Also, the halogen projector is not meant for an HID bulb because halogens do not put out as much light and as wide of an angle as HIDs. This will cause the screwed up cut off line this guy is experiencing.. That means that what he needs is a retrofit. He should look into morimoto they have good designs or also, the Acura TL HID projector is one of the best ones out there. And contrary to what ImTheDevil believes, they will shine just fine through his lenses.
